摘要:
There is a request for charging and discharging of a lithium-ion battery with as less degradation as possible. In an operation using only binary values as in conventional technology, however, in a charged state in which the battery is used, there is a high possibility that the battery is used toward accelerating the degradation thereof. In a power distribution device for distributing power between a plurality of batteries and a plurality of customers, when distributing the power of the batteries to the loads of the customers, by being based at least on the degradation information of the batteries, the state of charge, and the temperature data of the batteries, a battery discharging function is achieved that makes the degradation of the batteries minimum.

An illumination light-emitting member is made up of an LED group obtained by connecting a plurality of LEDs in series with each other, and illuminates the surface to be sensed including an image.

A booster circuit serves as a power supply circuit for the LED group, and generates a high voltage by adding a predetermined power supply voltage in the apparatus, and a frequency-divided pulse obtained by frequency-dividing a predetermined pulse output from the drive circuit.

An image sensing apparatus which performs fast data processing without suffering an increased manufacturing cost. The image sensing apparatus senses an object and produces an image data signal screen-by-screen. In one embodiment, an image sensing apparatus for producing an image data signal includes an image sensing unit, a signal processor, a main buffer memory, and an image data processing circuit. A first group of processed pixels having the size of a first matrix is stored in the main buffer memory. The image data processing circuit receives a second group of pixels having the size of a second matrix from the first group stored in the main buffer memory. Included in image data processing circuit is a sub buffer which is initially filled with the second group of pixels. As pixels are processed and removed from the sub buffer, a third group of pixels is provided from the main buffer which is equal in size to a horizontal row or a vertical column from the second group.
摘要:
An image sensing apparatus for sensing an object and for transmitting the image information to a bus line as digitized data. The image sensing apparatus includes a solid state image sensor. The sensor has a plurality of light-receiving elements aligned in a matrix form and stores information charges produced by each light-receiving element in response to received light. A driver provides the solid state image sensor with a clock pulse and causes it to sequentially output the information charges stored in the individual light-receiving elements in accordance with the clock pulse. A signal processor produces image signals in a predetermined format in response to the information charges from the solid state image sensor. An A/D converter quantizes the image signals produced in the signal processor and produces image data corresponding to each light receiving element. An output interface outputs the image data from the A/D converter to the bus line. The output interface operates between a supply voltage and a first ground voltage. The solid state image sensor and the signal processor operate between the supply voltage and a second ground voltage. The second ground voltage has a lower potential than the first ground voltage.
