Abstract: A distributed telephone communication system (50) in­
terconnects telephone units (52) via a single transmission 
line (56) providing full duplex communication between any 
pair of telephones (52). Each telephone (52) is coupled to 
the transmission line (56) by a control unit (54) which pages 
other control units (54) to initiate a telephonic communi­
cation. Each control unit (54) has an identification number 
and circuitry (60) for recognizing the identification number 
contained within a paging signal so as to initiate a re­
sponse. In a separate spectral portion of the transmission 
line (56), there are provided sets of analog communication 
channels each of which has upper and lower spectral por­
tions to provide two-way communication in opposite direc­
tions between a pair of tehephones (52) engaged in commu­
nication. A transmitter (22) and a receiver (23) in each of the 
control units (54) is provided for the communication of ana­
log signals of both voice and date via the voice channel. 
Each control unit (54) includes circuitry (1A, 1B) for tuning 
the transmitter (22) and the receiver (23) to the selected 
channel in accordance with digital data transmitted via a 
transmission line (56) and specifying a selected one of the

Title: Medium and method for erasably recording data by viscoelastic shear deformation (cold working)
IPC: G11B7/007
Filed: 1987-09-30
Abstract: An erasable optical data storage medium has a polymer dual recording layer (10) including an expansion layer (14) bonded to a retention layer (16), each of the layers dyed to selectively absorb light in respective narrow wavelength bands. The retention layer (16) has a glass transition temperature substantially above the glass transition temperature of the expansion layer (14), and is capable of undergoing substantial viscoelastic shear deformation (22) while below its glass transition temperature. A first laser beam B1 heats the expansion layer (14) causing it to expand and cause viscoelastic deformation in the retention layer (16) while the retention layer (16) is below its glass transition temperature. A second laser beam B2 is used to heat the retention layer (16) above its glass transition temperature and relax the deformation (22), erasing the medium.

Abstract: An integrated circuit for a CD player includes an 
EFM decoder (1) which converts an EFM signal inputted 
from a compact disc into symbols. Data of subcodes 
which includes first , second and third areas is 
outputted from the EFM decoder and stored in a first

circuit and data of the subcodes is selectively 
outputted from a selector (37) to a second shift 
register (42) which outputs the inputted data in 
response to clocks from the microcomputer to the same 
in a bit-serial fashion.

Abstract: A bi-stable hinge unit (10) of elastic material connects 
two inflexible end portions (12, 13) to take up two 
stable positions on either side of an intermediate 
unstable position. The hinge unit (10) comprises two 
equal elements (14, 15), each of which having two 
cantilever arms (18, 20), linked to each other by two 
folding lines (22) acting as a "living" hinge. A

defined by said folding lines (22). The elements (14, 
15) are arranged substantially parallel to each other 
with a distance therebetween and forming the main hinge 
line between said end portions (12, 13). By swinging 
said end portions (12, 13) toward each other along said 
main hinge line, the four cantilever arms (18, 20) will 
start to deflect and act as springs and the two 
triangular plates (16) will rotate through approximately 
180° in a plane normal to the elements (14, 15).

generating circuit (2a) generates an address 
corresponding to each sweep timing dot and to the 
magnitude of an input signal, each time it receives the 
timing signal. An image memory (3) stores data in the 
address generated by the address generating circuit

timing signal, performs a predetermined computation on 
that data stored in the image memory (3) and generates a 
result of computation. The computation result 
reprsents the frequency of the same address generated 
for each sweep timing dot. A display unit (4) displays 
the input signal with a luminance level corresponding to 
the computation result.

Patent EP-0357285-A3 (EP)
IPC: H02J3/00
Filed: 1989-08-15
Abstract: A power supply for outdoor lighting systems 
accepts alternating current at mains voltage. The power 
supply uses a digital switching means (151) to convert this 
current into a lower voltage at a higher frequency. 
Typically, these values are 28 volts at 20kHz. This high 
frequency signal is then supplied to the lights (3) through 
a transformer (152). The use of a higher voltage than that 
normally used for such systems improves the operating 
efficiency of the lighting system and allows lights to be 
placed at a greater distance from the power supply. The 
higher frequency signal reduces the bulk and cost of the 
transformer (152). The voltage and current supplied to the 
lights can be altered by changing the frequency (157) of the 
signal entering the transformer. A feedback circuit 
monitors the signal supplied to the lights and automatically 
varies the frequency so as to keep the voltage (156) and 
current (155) within predetermined operating limits.

Title: Method for monitoring telephone status changes
IPC: H04M11/06
Filed: 1989-08-01
Abstract: A method is disclosed for controlling the monitoring of 
telephone status changes by an associated processor. A 
status change inquiry message is transmitted from the 
associated processor to the telephone and is utilized to 
set an interrupt mode within the telephone (42). The 
status change inquiry message may also include a timer 
setting value (48) which is utilized, in a preferred 
embodiment of the present invention, to determine a 
maximum duration for the interrupt mode. In response to a 
change in telephone status (52), or the termination of the 
timed interrupt mode (54), a single phone status message 
(56) is sent to the associated processor and the interrupt 
mode is terminated. In this manner, a change in phone 
status may be determined by the associated processor 
without the necessity of continuously polling the tele­
phone. Further, any transmission of a phone status change 
terminates the interrupt mode and prohibits the telephone 
from continuously interrupting the associated processor 
with status change messages.
