A menu driven reprogrammable drug pump is provided with a memory, such as flash memory, a display, a keyboard, and a communications port to allow a generic pump to be programmed with a desired pump application (therapy) program and patient specific settings. Programming and data transfer with another pump or a computer to and from the patient pump is by the communications port that allows local and/or remote communications with the pump. Flash memory stores the pump application program during use. Patient safety is provided by a cassette identification system, an occlusion detection system, and a latch/lock detection system. Automated testing of the pump is by a closed loop testing system.

A portable data terminal including a multi-core processor having at least a first core and a second core, at least one illumination assembly and at least one imaging assembly and data storage means configured to store a plurality of program instructions, the program instructions including at least one one-dimensional decoder and at least one two-dimensional decoder.

Low power multi-core decoder system and method

An infusion device with a disposable administration set which is inexpensive to manufacture. In the preferred embodiment of the present invention the disposable administration set has a plurality of elongated cam followers connected to a plate assembly, wherein the cam followers are displaced in a predetermined sequence and forced against a delivery tube by cam means driven by rotary drive means. The disposable administration set is injection molded as a single integral piece. The disposable administration set includes adjustment spacers disposed between the plate assembly and the cam followers which adjust the distance between them to keep the device accurate. In the preferred embodiment of the present invention the cam means are configured to provide fluid delivery at a consistent and uniform rate.

Infusion device with disposable elements

There is described an imaging apparatus having an imaging assembly that includes an image sensor. The imaging apparatus can capture a frame of image data having image data corresponding to a first set of pixels of the image sensor. The imaging apparatus can capture a frame or image data having image data corresponding to a second set of pixels of the image sensor.

A flash photographing system includes a camera body, a flash controller connected to the camera body and three flash devices: the first flash device is directly mounted on the camera body; the second flash device is mounted on the flash controller; and the third flash device is connected through a suitable cord to the flash controller. A microcomputer is provided in the camera body and also in each of the flash devices so as to control the three flash devices in various different modes of operations, such as simultaneous flash mode, sequence flash mode, and yet providing an appropriate amount of light for the proper exposure.

Flash photographing system

A camera system operable with data carried from a camera accessory to a camera body. The camera accessory has a ROM for storing various data at a plurality of addresses, respectively, each of which data consists of a plurality of bits, and a coupling terminal for receiving a train of clock pulses from the camera body. A circuit is also provided for sequentially designating the address of the ROM one by one to permit the ROM to output data stored at the designated address. In the circuit, an address signal is formed in response to the clock pulses, received through the coupling terminal, for designating an address. The data derived from the ROM are transmitted to the camera body.

Camera system operable by carrying data from a camera accessory to a camera body

From a data transmission device to a camera system including a camera and electronic flash device, operation instruction data such as set or calculated exposure control data, shutter release data instructing the operation of the camera system, flash emission testing data and the like are serially transmitted in the form of infrared light signal. When the reception of these data is completed, the camera starts its operation to control given operation of the camera system such as the exposure initiation of the camera, test light emission of the electronic flash device and the like in accordance with received data. Additionally, in the case where the data transmission device is an exposure meter which measures flash light and daylight, flash light emission operation or light emission interruption operation of the electronic flash device is controlled in accordance with the determination whether the exposure control data calculated and transmitted to the camera system is for the daylight photography or the flash light photography.

Data transmission system for a camera

A multi-point photometric apparatus for use in a camera or the like operative to measure the luminance of several divided areas in an objective field. Among the luminance signals produced by the photometric circuit for the several areas, a signal from one area which is used for automatic focus adjustment is designated as a reference value, and the maximum and minimum values of luminance signals and the differences of these from the reference value are evaluated. The reference value and differences in the form of digital data and information on the film latitude are processed with a microprocessor to calculate the exposure value. The exposure value is modified to an extent that the reference remains within the film latitude.

Multi-point photometric apparatus

A camera system is provided that permits memory data dedicated to particular camera accessories to be transmitted to the camera body for enabling the operation of the camera. The camera accessories can carry dedicated information or variable information to the camera body. Synchronization between the camera accessory and the camera body can be provided by a train of clock pulses. Information can be programmed in a fixed memory circuit to insure that only a particular accessory so designated will provide information to the camera body to prevent any erroneous inputting of data from a plurality of camera accessories that are contemplated for use with a particular camera body.
