Enhanced sleep mode in radiocommunication systems.

Abstract: A method and system for providing an enhanced sleep mode for remote units in a radiocommunication system are described. Measurement periodicity for control channels of neighboring cells is optimized. Paging frame classes can also be temporarily modified to extend sleep periods.

Sleep detecting apparatus

Abstract: Movement of a person in bed is detected without contacting the body, and time measurement is reset and started newly by a timer every time a detected movement exceeds a predetermined set value. When the measurement time of the timer exceeds a set time predetermined, it is judged that the body has fallen asleep on the bed. Meanwhile, absence or presence in bed and rough body movement are judged by detecting the fine body movement propagated by the functioning of heart and breathing of the body.

Method and system of data transmission and reception in a mobile station within a radio telecommunications system

Abstract: A method and system of transmitting and receiving data in a mobile telecommunications system which reduces power consumption in mobile stations operating within the system. Mobile stations are divided into a plurality of sleep groups and a sleep message, which is transmitted in the control channel Overhead Message Train (OMT) as a Global Action Overhead Message (GAOM) is introduced. The bits of the sleep message contain data fields which indicate to mobile stations in each of the sleep groups when to monitor the control channel on which the sleep message was transmitted.

The effect of the timing, quality and quantity of sleep upon the depression (masking) of body temperature on an irregular sleep/wake schedule

Abstract: Eight subjects were studied on an irregular sleep/wake schedule which was designed so that prior wake time and the time of day when 4-h sleep periods were taken were both balanced. Rectal temperature and the sleep EEG were measured throughout the 8-d protocol. A purification method was used to estimate the depression of rectal temperature (masking) caused by the first and second halves of each 4-h sleep period. On average this was 0.187 +/- 0.015 degrees C during the first 2 h and 0.262 +/- 0.017 degrees C during the second 2 h. Masking increases beyond the first 2 h of sleep, but any effects due to the phase of the rectal temperature when sleep is taken are very weak. However, masking did increase (that is, the temperature was depressed more) when the amount of prior wake time was greater than 4 h. When the effects of sleep content variables were considered also, masking was still greater in the second half of sleep and tended to increase with the amount of slow-wave sleep, but it decreased with increasing amounts of time awake during a sleep period (sleep latency or sleep discontinuity). Some implications of these results for the mechanism of sleep-induced masking are considered.

Multiplex communications equipment

Abstract: PURPOSE:To obtain a multiple communications equipment in which the equipment enters a sleep state surely even when a reception of a sleep instruction from a master station is failed and a wakeup signal is sent even from the fail safe state to restart communication with the master station. CONSTITUTION:When a communication signal is not consecutively sent to a fail safe means (part of sleep wakeup fail safe controller 28) for a predetermined time through a communication line, the means stops a clock oscillation circuit 8 to transit a concerned slave station in a low power consumption state regardless of the presence of a sleep instruction from a master station. Then a wakeup output means (part of the controller 28 provides an output of a wakeup signal when the communication signal is not sent consecutively to the means for a predetermined time or over through the communication line and an entry comes from an input switch 15 of a terminal equipment of said slave station.

Output device and its control method, information processing method and device therefor and network system

Abstract: PURPOSE: To set a suitable time interval for the operating environment of a recording device by updating the time interval set for shift to the power saving control based on the interval set for receiving data from an external device. CONSTITUTION: A print holding state is set when the reception of data from a host computer 1300, the print processing of the data and a panel operation given to an operation pattern 1200 are all finished. At the same time, a time counter C included in a RAM 1108 is initialized. Then the print holding state shifts to a sleep state when the coincidence is secured between the value of the counter C and two values of an NVRAM 1106. The present value of the counter C is written in the NVRAM 106 as a time interval D' to the next sleep state when a job is continuously carried out. When a sleep shift holding state is canceled, the interval D' is written in the NVRAM 1106 as the set value D. Thus the time needed for shift to the sleep state is automatically updated according to the access frequency to a printer in a system. Then the power saving can be effectively controlled.

Digital signal processor

Abstract: PURPOSE: To reduce the power consumption of the whole digital radio terminal by outputting a master clock request signal only in the processing operation of a DSP. CONSTITUTION: The clock control part of the digital signal processor consists of a clock generation part 1, a sleep setting part 2, a sleep resetting control part 3, and a master clock request part 4, and a sleep is set by software and an external sleep request to outputs the master clock request signal 9 of 'LOW'. At an interruption request 11, on the other hand, the master clock request signal 9 of 'H' is outputted. Only when the request signal 9 is 'H', the master clock is supplied to the DSP outside the DSP, so that the power consumption of the radio terminal can easily be made low. COPYRIGHT: (C)1995,JPO

Method of controlling air conditioning apparatus

Abstract: PURPOSE:To lower the sound of a refrigerant during the switching of a four-way valve by setting time to the switching of the four-way valve longer than a specified time at the starting or ending of defrosting being confined to the setting of an OFF timer. CONSTITUTION:After the stoppage of a compressor 1 being confined to a sleeping time. the switching of a four-way valve 2 is awaited longer than a specified time until there is no pressure difference between an outdoor side heat exchanger 5 and a room side heat exchanger 3. In other words. to check for the sleeping time, a judgment is performed on whether a OFF timer is set for a 'sleeping timer' or the like or not. The switching timing of the four-way valve 2 is delayed being confined to the time when the OFF timer is set until the pressure difference of a refrigerant gas balances. This enables the preventing of the sound of the refrigerant to be generated from a difference of the refrigerant pressure in the switching of the four-way valve 2 thereby keeping sound sleep from being disturbed during the sleeping.

Automatic storing mechanism for main contents of storage

Abstract: PURPOSE:To provide a personal computer which can store the data more surely when a sleep mode lasts for a long time. CONSTITUTION:When an idle time lasts for a certain period of time and the count value of a sleep timer 10 reaches a set level, a sleep mode changeover action restart timer 11 starts its operation. When the operation of the timer 11 lasts up to a set time, the action mode of the timer 11 is once changed so that the ordinary processing ability is secured. A system program confirms the changeover factor and starts the corresponding program and sets a sleep mode to reduce the power consumption if a device is left as it is. Furthermore, the system program automatically copies the data stored in a main memory into a nonvolatile storage device before these data are lost if the device is left as it is even after the action mode is switched to the sleep mode.

Image forming device and fixing device

Abstract: PURPOSE:To avert the complicatedness to an operator in predicting and inputting the optimum time of the on/sleep of the device by changing over the on- state and sleep-state of the device according to the learning result of the image forming time. CONSTITUTION:A time control CPU 62 is capable of learning the image forming time. This CPU 62 monitors whether the sleep time to calculate is attained or not from the result of the image forming time learning. The time control CPU 62 turns off a power feed section 32 for normal through an on/sleep changeover signal line 37 at the sleep time. This state IS the sleep-state and only the time management section 29 is under operation. The time control CPU 62 monitors whether the on-time to calculate is attained or not from the result of the image forming time learning. The time control CPU 62 turns on the normal power feed section 32 through the on/sleep changeover signal line 37 at the changeover time to on. A main unit 1 is put into ordinary use state by this operation. The main unit 1, then, executes printing processing.

Local area network line system

Abstract: PURPOSE:To reduce the consumption current of a reception circuit during SLEEP by switching a system to a signal change detection circuit with less current consumption during SLEEP switching it to the reception circuit at regular time after WAKE-UP is detected. CONSTITUTION:A sleep/wake-up (SLEEP/WAKE-UP) control means 61 in a communication control circuit 60 sets a SLEEP command signal S60a to 'L' when SLEEP control CS comes from host CPU. Power current is interrupted and consumption current becomes little in a differential comparator 40. The control means 61 sets an initialization signal S60b to 'L' and reelases the resetting of an edge detection circuit 70. When the edge detection circuit 70 detects the transmission of a message on BUS 21 and 22, a WAKE-UP command signal S73 becomes '1' and the communication control circuit 60 sets the SLEEP command signal S60a to 'H'. Thus, the differential comparator 40 starts the reception of input.

Sleep preventive alarm device and method for deciding state of shift to sleep

Abstract: PURPOSE:To emit an alarm by perceiving the moment a driver begins to assume a sleeping state from brain wave frequencies or the number of heart beats. CONSTITUTION:This device has a brain wave detector 2, a brain wave frequency discriminating means 3 for identifying whether the driver is in the state of shifting into sleep or not in accordance with the signal from the brain wave detector 2 and an alarm generating means 4 for emitting the alarm in accordance with the signal form the brain wave frequency discriminating means 3. The brain wave frequency discriminating means 3 is constituted to decide 10Hz frequency as the decision value of the sleep state in identification of whether the state of shift into the sleep or not in accordance with the signal from the brain wave detector 2. The brain wave frequency discriminating means 3 outputs a signal to the alarm generating means 4 when the signal from the detector exceeds the value. As a result, the accident occurring in sleeping is prevented.

Abstract: PURPOSE:To provide the issuing system of a suspending instruction with time-out function where the restart by a wide range of sleep release conditions is enabled by enabling the restart after a suspension for the use of not only an external interruption but also both of an indefinite designation and a time-out designation. CONSTITUTION:A function of a time-out 3 is added to a sleep instruction 2 which is applied to the equipment control where a microcomputer, etc., is used and in which the execution of a program is temporarily stopped and the processing of a CPU 1 by the control of a computer is made to be in a suspending state, and an external interruption 4 or an event signal is inputted from the outside. The restart conditions of a system by a sleep release are made to be three kinds of the time-out 3, the input of an event signal 5, in addition to a conventional external interruption 4.

Method of controlling air conditioner

Abstract: PURPOSE:To cause a room temperature to rapidly reach a predetermined set temperature irrespective of setting of a sleep timer function by delaying starting of a set temperature correction of a room temperature effected by a sleep timer a period of time. CONSTITUTION:In the case where a sleep timer acts or time associated with the sleep timer is up, an air conditioner is stopped and the sleep timer is restarted without being put out of function, counter means 6 delays starting of a set temperature correcting function of the sleep timer, for example, 30 minutes when operating condition judging means 5 confirms that a set temperature is high and the sleep timer is not put out of function. In the meantime, a room temperature is decreased through room temperature control effected by a room temperature sensor 10 and is held at a set temperature as it is for 30 minutes when a predetermined period of time lapses and correction of sleep set temperatures is started. After 30 minutes lapses, the set temperature is raised 0.5 deg.C, and thereafter such action is repeated and counting of the timer is continued.
