Electronic device with display viewable from two opposite sides

Abstract: An electronic device (100) includes a processor (808) for processing a message (110), and a display (114) electrically coupled to the processor for displaying an image including the message. The display is constructed and arranged such that the image is viewable from first and second sides (116, 118) of the display, the first and second sides facing opposite one another.

Electronic book and method of displaying at least one reading metric therefor

Abstract: A method of displaying at least one reading metric in an electronic book (100) includes reading machine-readable data from a machine readable storage medium (136) installed in the electronic book. The machine-readable data is representative of text of a book. At least one page of the text represented by the machine-readable data is displayed using the electronic book (100). A reading pace of a user is monitored over the at least one page, and the reading pace is displayed by the electronic book. An amount of the book which can be read at the reading pace during a remaining powering time for a battery which powers the electronic book can also be displayed. An estimated completion time for a portion of the book can be calculated and displayed based on the reading pace.

Ripple detector for automotive alternator battery charging systems

Abstract: Detector (28) monitoring the voltage ripple in the rectified electrical output signal of an alternator (22) in a multiphase alternator battery charging system. A circuit monitors the undulating alternator output signal and produces a signal level in response. To correct the detector operation for various magnetic phenomena present in the alternator, a first circuit measures the rotational speed of the rotor and produces a proportional signal. A second circuit determines the excitation current supplied to the field coil. The measurement and determination are separately weighted and combined to form a corrected comparison threshold value. A variable threshold circuit combines the signal proportional to the rotational speed of the rotor and the determined field coil excitation current to produce a combined signal level. Comparison means compare the signal level from the monitored alternator output signal with the combined signal level and produce an output signal level indicative of the detection of a voltage ripple in excess of the combined signal level. The output signal is corrected for the effects of significant alternator performance characteristics.

Scroll Apparatus and Method for Manipulating Data on an Electronic Device Display

Abstract: A method (700) and apparatus for adjusting the data presentation on the display (102) of an electronic device (100) is provided. A user touch scroll input device (101) is provided on the electronic device (100). A user then manipulates the user touch scroll input device (101) with a finger (116) or stylus to alter the presentation of data, which may include navigating a list of data elements (112) or altering the image magnification of an image (113) or the output of an on-board camera. Length of stroke, final point of user contact, direction of user motion, and an optional timer are all used to control the alteration of the data presentation. For example, a timing module (109) can initiate a timer with the user makes contact with the user touch scroll input device (101). While the timer is running, the data presentation is altered at a first rate. Once the timer expires, the data presentation is altered at a second rate.

Method for autonomous handoff in a wireless communication system

Abstract: A method and apparatus for handoff to a rescue channel is introduced without the need to send and receive handoff control messages. In the preferred embodiment of the present invention, coordination of the rescue procedure at the infrastructure (450, 350, 351, 352) and mobile station (330) is provided first by disabling the mobile transmitter followed by subsequent detection of signal loss and frame erasures at the serving cells (311), then by enabling the mobile transmitter followed by subsequent detection of signal by a rescue cell (310, 312, 313, 314), and finally by enabling the rescue cell channel transmitter followed by subsequent detection and reception of signal and frames by the mobile station (330).
