Title: An automatic gain control (agc) for frequency hopping receiver
IPC: H04B1/713
Filed: 1989-10-21
Abstract: The invention is an automatic gain control (AGC) sampling 
structure for use with frequency-hopped high frequency waveforms 
containing known transmitted signals embedded within communi­
cation traffic. The sampling structure is a digital structure 
and an automatic gain control selection algorithm used in 
conjunction with a standard close loop analog automatic gain 
control circuit in which the automatic gain control generator 
(26) detects the received audio level and generates a direct 
current control voltage for controlling an amplification stage 
(20). This automatic gain control voltage is sampled during 
the reception of known transmitted signals to provide a series 
of independent automatic gain control samples to a digital 
controller (34). The digital controller (34) determines the 
optimum automatic gain control voltage based on a selection 
algorithm which uses the technique of altered statistics to 
select the correct ordered sample to provide the optimum 
automatic gain control level for the receiver. The standard 
automatic gain control loop is then interrupted and the optimum 
automatic gain control voltage selected by the digital con­
troller (34) is coupled to provide the direct current control 
voltage to the amplification stage (20).

Title: Magneto-optical recording system having medium with domainless control layer
IPC: G11B5/02
Filed: 1989-03-15
Abstract: An information storage system records 
on a medium with a magneto-optical 
storage layer (30) and a ferrimagnetic 
control layer. A higher power 
write beam is used to impose an upward 
magnetic orientation and a lower 
power write beam is used to impose a 
downward magnetic orientation in the 
domain. The control layer (50) has an 
initial downward magnetic orientation, 
the magnetization of regions of the 
control layer (50) can be inverted to an 
upward orientation temporarily 
while the region is heated above a 
compensation temperature. The 
magnetization of the region is restored to 
its initial downward orientation 
upon restoration of ambient temperature 
since neither the higher power nor 
the lower power write beam heats the 
control layer to its Curie temperature. 
The distributed optical and thermal 
properties of the medium are selected 
so that, upon heating of the medium 
by dissipated laser energy, the peak 
temperature of the control layer (50) occurs 
after the peak temperature for the 
storage layer (30). When the higher power 
write beam is used, the domain cools 
through its Curie temperature before 
the corresponding region cools through 
its compensation temperatures so that 
an upward magnetic orientation is 
established in the domain. When the 
lower power write beam is used, 
the domain cools through its Curie 
temperature after the corresponding 
region cools through its compensation 
temperature so that a downward magnetic 
orientation is established in the 
domain.

Title: Hearing aid programming interface and method
IPC: H04R25/04
Filed: 1989-05-04
Abstract: A method of programming a programmable hearing aid is 
disclosed. The programmable hearing aid has a serial data 
interface for receiving data transmissions, a decoder for 
decoding data transmissicns, a program memory which stores 
program data values received via the serial interface, and 
read control logic that transmits the program data stored in 
the program memory when the decoder detects the receipt of a 
predefined read signal. Programming begins with the sending 
a set of program data values to the programmable hearing 
aid, preceded by a predefined write signal. The hearing aid 
automatically mutes or inhibits its operation upon receiving 
the write signal. A first checksum value corresponding to 
the program data values sent to the programmable hearing aid 
is calculated. Next, the data stored in the hearing aid is 
checked by sending a predefined read signal to the hearing 
aid, causing the hearing aid to transmitting the program 
data stored in its program memory. A second checksum value 
corresponding to the program data transmitted by the hearing 
aid is calculated and compared with the first checksum 
value. If the first and seccnd checksum values do not match 
an error signal is generated and the hearing aid remains 
muted. If the checksum values do match, an unlock signal is 
sent to the hearing aid, causing the hearing aid to resume 
normal operation.

IPC: F16H59/62
Filed: 1989-10-03
Abstract: An electronic control system for scheduling 
gearshifts in a four speed automatic transmission 
includes storing in electronic memory accessible to a 
microprocessor, six functions relating vehicle speed to 
throttle position, one function being related to each 
upshift and downshift. Gearshifts are made by probing 
computer memory with current values for throttle position 
and vehicle speed, and determining on the basis of the 
stored shift schedule whether an upshift or downshift is 
required. Upshift points are determined also on the 
basis of the maximum engine speed when a wide open 
throttle condition is detected. Ambient barometric 
pressure alters the vehicle speed and engine speed 
attained at high altitude in comparison to those speeds 
that result for the same throttle position at sea level. 
Therefore, shift points defined by the schedule on the 
basis of vehicle speed and throttle position, and shift 
points related to wide open throttle conditions and 
engine speed, are corrected for altitude or barometric 
pressure changes from a reference barometric pressure at 
which the shift points are determined for the functions 
stored in computer memory.

Patent EP-0401564-A3 (EP)
IPC: B60C7/00
Filed: 1990-05-16
Abstract: A side web non-pneumatic tire ("SWNPT") is integrally molded from a stiff, resilient elastomeric material with particular specifications, to form a unitary honeycomb structure bounded by integrally molded outer and inner cylindrical coaxial and coextensive members ("hoops"), and, a single side web member. The outer hoop is supported and cushioned by the honeycomb which comprises a plurality of circumferentially spaced apart, angularly oppositely directed planar rib members (ribs) bounded by the side web on one side only. The side web, preferably on the outboard edge of the hoops, connects the hoops near their outboard edges. The opposite side surfaces of the side web lie at an angle  theta  in the range from 0 DEG  to 30 DEG  on either side of vertical to the rotational axis of the SWNPT. The ribs extend axially along the inner and outer hoops, connecting them, and the outboard edges of all the ribs lie upon the inboard face of the web. The ribs on each side are angled at opposite angles in the range from 15 DEG  to 75 DEG  to radial planes which intersect them at their radially inner ends. A rubber tread is secured to the outer surface of the outer hoop. The coaction of the structural elements of the SWNPT provide a load-supporting structure which, in operation, is subjected to continuous compression and tensile forces as it travels over the ground. Deformation and buckling characteristics of the SWNPT are derived from the honeycomb structure of an elastomer which provides the SWNPT with "ride" and "handling" comparable to those of a conventional pneumatic tire. The outer hoop has a vulcanized rubber tread secured to the hoop's outer surface to withstand travel over a road surface. The unribbed face of the single side web may be faced with an elastomeric sidewall to resemble the sidewall of a conventional pneumatic tire.

Title: Radio frequency energy detection circuitry
IPC: H04B17/00
Filed: 1990-03-01
Abstract: Radio frequency energy detection circuitry (10) changes 
the logic state of its output signal at a terminal (12) from 
an initial state to a second state in response to received radio 
frequency energy exceeding a first predetermined power level. 
The circuitry (10) does not respond to fades in such received radio 
frequency signal because the second state of the output signal 
is prevented from reverting to the initial state until the power 
level of the received radio frequency energy falls below a second, 
lower predetermined power level. The input energy is converted 
into a voltage by a detector diode (18). This voltage is compared 
(26) with the prevailing threshold voltage (V R ) to determine the 
output logic state. The output logic state is fed back by 
a resistor (R S ) to the threshold voltage input terminal (25) 
and is such as to establish the second, lower predetermined 
power level in response to the received radio frequency energy 
exceeding the first predetermined power level.

Title: Epicyclic drive
IPC: F16H1/32
Filed: 1992-08-12
Abstract: An inscribed meshing speed increasing and reduction gear construction in which external teeth (for example, a1 and a2, b1 and b2, and c1 and c2) cut at the same position during processing are not simultaneously meshed with (outer pins 111 of) internal-tooth gear during operation in order to improve the accuracy after completion of assembling even if the gear is cut by a machine of similar processing accuracy. Thereby, (although it seems to be contrary to a conventional idea that said external teeth cut at the same position should be simultaneously meshed with the internal-tooth gear), the actual accuracy after completion of assembling can be improved. In this case, when both the number of teeth (24 in Fig. 1) of external-tooth gears 105a and 105b, and a difference in the number of teeth (4 in Fig. 4) between the external-tooth gear and (outer pins 111) internal-tooth gear, are set to integer times of the number (2 in Fig. 1) of the external-tooth gears, the external teeth of the external-tooth gears and various holes formed in the external-teeth can be all simultaneously (by one setting) cut, and remarkably improving the accuracy of the positional relationship between the external teeth and various holes. <IMAGE>
