Title: Photovoltaic cell with thin cds layer
Inventor: JORDAN JOHN F
IPC: H01L31/073
Filed: 1993-01-13
Abstract: The photovoltaic panel of the present invention is initially formed with a CdS and CdTe layers in overlying relationship on a glass substrate and the effective thickness of the CdS layer is reduced during a two-step annealing process to both form larger diameter CdTe crystals (36A, 36B, 36C, 36D) and substantially reduced thickness CdS layer (32) by diffusion into the CdTe layer (44) such that majority of sunlight having a wavelength less than 520 nm passes through the CdS layer (32) to the photovoltaic junction.  The p-type CdTe material (44) is first heat treated in an oxidizing environment to oxidize impurities and thereby substantially enhance the desired electrical properties of the p-type CdTe material. The heat treated material is then annealed in a substantially inert environment to increase crystal sizes and thereby enhance photovoltaic efficiency. During the heat treating step, an oxidation gradient may be maintained through the thickness of the p-type CdTe layer (44).

Abstract: The mass of a tire can be reduced by the use of a belt package having a combination of a steel reinforced inner (first) belt ply and an aromatic polyamide reinforced outer (second) belt ply.  The belt plies are to be made without the cost of having folded belts or any other non-standard construction features. The improved endurance of the tire of this invention is assured by the physical features of the individual belt plies as well as required physical relationships between belt plies.  The breaking strength, the spacing and the angle with respect to the tire's mid-plane for the reinforcing members in each belt ply are defined.  The strength per unit width of the aromatic polyamide reinforced second belt ply is made to be within 30 percent greater than the strength per unit width of the steel reinforced first belt ply to improve tire endurance.  A functional relationship using the bending stiffness values of each belt ply and the composite belt package shear stiffness is also defined to improve tire endurance. The difference between the bending stiffness values for each belt ply about a lateral y-axis (BY1-BY2) as well as the composite shear stiffness with respect to the z-axis (CGZ) were found to correlate very well with high impact endurance values.  The tire of this invention uses angles of the aromatic polyamide reinforcing members from the mid-plane greater than the angles of the steel reinforcing members from the same mid-plane by 1 to 8 degrees.  Preferably the angle of the aromatic polyamide reinforcing members is 3 degrees larger than the angle of the steel reinforcing members from the mid-plane.

The transfer paths (10, 16) of a function block of the first type are isolated from each other for enabling shutting down such an erroneous transfer path from traffic by software control.

Title: Electronic animal control system with masking signal generator
Inventor: TOUCHTON SCOTT F
IPC: A01K15/02
Filed: 1996-04-01
Abstract: A disruption generator is provided for use in an electronic animal confinement system for preventing undesirable correction of the animal in the vicinity of incidental conductive structures capable of coupling and re-radiating a transmitter signal for controlling the animal.  The disruption generator produces a disruption signal for masking, preventing, or otherwise interfering with reception of the transmitter signal by an animal control receiver device mounted on the animal.  The disruption generator can be connected to such incidental conductive structures as utility conduits, door frames, household wiring, and the like, to prevent undesirable correction of the animal in the vicinity thereof due to inductive or resonant coupling of the transmitter signal by such structures.  Additionally, the disruption generator can be connected to a disruption antenna for providing a portion of the animal control area, for example, a corridor across the perimeter of the area, in which the animal control receiver will not apply a correction stimulus to the animal.
Patent CA-2178506-A1 (CA)
Inventor: DOVE DONALD C
IPC: H02J3/18
Filed: 1994-12-07
Abstract: A microprocessor (42) is coupled to sense the current and voltage in an AC line (11) at a high sampling rate and to determine the power factor. In one embodiment the primary (83) of a transformer (84) is coupled across the power lines, and at least two capacitors (86, 88), forming separate switching paths, are coupled to the secondary (85) of the transformer.  High speed switching circuitry under the control of the microprocessor alternately charges and discharge the capacitors (86, 88) at varying frequencies, to alternately store energy from the power lines (11) when the variable load (32) is returning energy to the power lines, and to supply the stored energy back to the power lines when the variable load (32) is absorbing energy from the power lines (11). This corrects the power factor since the frequency of the high speed switching circuitry is varied with the varying reactance of the load. In another embodiment power factor correction is accomplished using a capacitor ladder (324), with different values of capacitance being switched into the circuit (328, 330) under microprocessor (344) control to maintain the power factor close to unity under varying load (322) conditions.
Patent CA-2179224-A1 (CA)
Inventor: WIEDEMAN ROBERT A
IPC: G01R29/08
Filed: 1996-06-17
Abstract: A  method  and  system  wherein  a  system  gateway  (18) determines, from closed loop power control information, a power density at an antenna (13a) of a user terminal 13. The gateway also maintains a record of a duration of time that the power density exceeds a specified threshold. The gateway determines if an averaged transmitted power density associated with the antenna of the user terminal will equal or exceed at least one of a predetermined threshold level, within a specified period of time, or an absolute threshold level.  If the gateway determines that a threshold will probably be exceeded if the call connection is maintained, the gateway terminates the connection prior to a time that the user terminal averaged transmitted power density level equals or exceeds the predetermined or absolute threshold level. A tone or a visual indicator may be employed to warn the  user  that  a  current  connection  or  call  will  be terminated. Provisions are made for allowing predetermined types of calls (e.g., emergency calls) to be made during a cutoff period wherein the user terminal is prohibited from placing further calls. It within the scope of the invention to perform the power density monitoring function also within the user terminal. In this case information may be transferred to the GW over a return link, and majority voting or some other technique can be employed by the GW before terminating the connection. In this case the power density determination made at the GW has priority over that made in the user terminal to prevent a user terminal from intentionally or inadvertently defeating the power density monitoring function.
