Granted: 1999-07-27
Abstract: A gfi wiring device is disclosed in the form of a duplex receptacle  for receiving the blades  of  a plug connecting an electrical appliance or other load to the circuit wherein the gfi device is connected.  The housing sections and components of the gfi are so configured and relatively arranged that the device may be automatically assembled by downward, vertical movement of the components  and the  front housing  section  in  a predetermined sequence relative to the rear housing section as the latter is positioned on a horizontal support.  The device is operationally tested after assembly is complete and, upon successful testing, the housing sections are permanently connected by heat deformation of portions  of  one  section  to  form  a  rivet-like  connection.          Reliability of testing is improved by breaking the usual traces on a printed circuit board extending between terminals to which jumper cables are connected to provide a fail-safe indication of circuit continuity through the jumper cables.  A deformable member movable to produce  a  fault condition  for test purposes,  as well  as electrical leads of a condition-indicating lamp are connected in the circuitry by solderless means,  being engaged between edge portions of terminal members and a separator member of dielectric material.

Title: Reducing interference from oscillators in electronic equipment
Inventor: LINDELL KARL BO
IPC: H04B15/04
Filed: 1995-04-20
Granted: 2004-04-13
Abstract: In an electronic apparatus including a reference oscillator and an interferi ng part that generates an interference signal having a spectral component withi n a receiver bandwidth, the reference oscillator supplying a reference oscillating signal to the interfering part from which reference oscillating signal the interference signal is derived, amplitude of the interference signal within the receiver bandwidth is reduced by angle modulating the reference oscillating signal with a sinusoidal signal to generate an angle modulated interference signal having a reduced carrier amplitude and modulation sidebands that are outside of the receiver bandwidth. The angle modulated interference signal preferably has a modulation index, (.beta.), that is close to a solution of the equation J0(.beta.) = O, where J0 is a Bassel function of the first kind. Angle modulation may alternatively be accomplished by applying direct frequency modulation to the reference oscillator with the sinusoidal signal to generate a modulated reference sign al and then applying the modulated reference signal to the interfering part, or by phase modulating the reference oscillating signal with the sinusoidal signal prior to supplying it to the interfering part. Where the interference signal has an interfering spectral component within a measurement bandwidth, the amplitude of the interfering spectral component is reduced by using a deterministic, non-noise modulating signal, such as a sawtooth waveform modulating signal, to angle modulate a clock signal from which the interference signal is derived.

Title: Temperature and volume control pressure balancing valve
Inventor: CLARE MANAMOHAN
IPC: F16K11/078
Filed: 1996-01-18
Granted: 2005-04-05
Abstract: An arrangement for temperature control and volume control of a pressure balancing valve used in tub/shower installations includes a temperature control handle that controls the mix of hot and cold water issuing from a pressure balancing cartridge within the valve and a volume control handle that controls the volume of the hot and cold water issuing from the cartridge. The volume control handle is connected to three lobes extending radially about the end of a shaft to which that handle is attached, the lobes being closely adjacent the face of the cartridge from which the water flows. The cartridge has a hot water outlet and a cold water outlet and in the neutral position of the volume control handle one of the lobes is located between the cartridge outlets and the other lobes do not block the outlets. When the valve is in operation one can rotate the temperature control handle to set the desired water temperature and one can rotate the volume control handle to set the desired water volume flowing from the cartridge. The two control handles are interconnected for conjoint movement so that when the temperature control handle is rotated to its "off" position to stop water flow the volume control handle is rotated back to its neutral position.

Title: Method and apparatus for copy protection for various recording media using a video finger print
Inventor: RYAN JOHN O
IPC: G06F21/10
Filed: 1996-05-22
Granted: 2001-01-23
Abstract: A method and apparatus for copyright protection for various recording media such as Digital Video Discs (DVDs) uses a combination of a Video Finger Print Signal and an Authenticating Signature to permit the player to handle either copy-protected or non-copy-protected media, in a manner that is difficult to compromise. Both a Video Finger Print Signal and an Authenticating Signature are recorded on the media only when copy-protection is required. The nature of this Authenticating Signature is such that it will not be transferred to illicit copies made on CD recorders. When either an original protected or an original non-protected disk is played, the presence or absence of the Authenticating Signature causes the player to correctly play the program video. All original DVDs therefore play normally. When a copy of a nonprotected CD is played, the absence of the Video Print Signal also causes the player to correcly playback the video signal data. However, when a copy of a protected CD is played, the absence of the Authenticating Signature causes the player to prohibit the disk from playing normally.
