Passenger service units in an aircraft are equipped with a passenger interface and supply adapter (10). Each adapter includes an individual processor (14) which is programmable independently of the aircraft central control through a programming input. The programmable interface (10) permits controlling passenger service components in the passenger cabin such as lamps in a cabin lighting system, a public address system, and so forth, directly by the interface (10) independently of the aircraft central control. The interface (10) with its own individual processor (14) and memory (15) is connected through a databus (11) to the aircraft central control (12), for example, for remote programming of the interface and for reporting the module's activities to the aircraft central control. The interface (10) reduces the memory capacity requirements for the aircraft central control and permits the individual programming of each passenger service unit also independently of any other passenger service unit thereby avoiding retesting of the entire cabin system when for example only one passenger service unit is reprogrammed.

A system and method for converting byte code of a first type into byte code of a second type. Byte code of a first type is received as input. The first byte code is converted into constituent byte code data elements that can comprise any logical unit or grouping of at least a portion of a software application. The first byte code data elements are mapped to data elements of a second byte code type. The second byte code data elements are assembled into a resulting second byte code.

A low density One-Time Programmable (OTP) memory is disclosed to achieve low gate count and low overhead in the peripheral circuits to save the cost. A maximum-length Linear Feedback Shift Register (LFSR) can be used to generate 2n−1 address spaces from an n-bit address. The registers used in the address generator can have two latches. Each latch has two cross-coupled inverters with two outputs coupled to the drains of two MOS input devices, respectively. The inputs of the latch are coupled to the gates of the MOS input devices, respectively. The sources of the MOS input devices are coupled to the drains of at least one MOS device(s), whose gate(s) are coupled to a clock signal and whose source(s) are coupled to a supply voltage. The two latches can be constructed in serial with the outputs of the first latch coupled to the inputs of the second latch.

An LDPC code encoding apparatus includes: a code matrix generator for generating and transmitting a parity-check matrix comprising a combination of square matrices having a unique value on each row and column thereof; an encoding means encoding block LDPC codes according to the parity-check matrix received from the code matrix generator; and a codeword selector for puncturing the encoded result of the encoding means to generate an LDPC codeword. The code matrix generator divides an information word to be encoded into block matrices having a predetermined length to generate a vector information word. The encoding means encodes the block LDPC codes using the parity-check matrix divided into the block matrices and a Tanner graph divided into smaller graphs in correspondence to the parity-check matrix.

System and method for improving the shaving experience by providing improved visibility of the skin shaving area. A digital camera is integrated with the electric shaver for close image capturing of shaving area, and displaying it on a display unit. The display unit can be integral part of the electric shaver casing, or housed in a separated device which receives the image via a communication channel. The communication channel can be wireless (using radio, audio or light) or wired, such as dedicated cabling or using powerline communication. A light source is used to better illuminate the shaving area. Video compression and digital image processing techniques are used for providing for improved shaving results. The wired communication medium can simultaneously be used also for carrying power from the electric shaver assembly to the display unit, or from the display unit to the electric shaver.

A video encoder is composed of a DC / AC prediction unit performing DC / AC prediction, a motion vector prediction unit performing motion vector prediction, and a memory. The memory is accessible from both of the DC / AC prediction unit and the motion vector prediction unit.
