Title: Method and apparatus for sensing the color of articles
Inventor: ALLAIRE GILLES
IPC: G01J3/46
Filed: 1993-04-29
Granted: 2002-08-20
Abstract: Method and apparatus for sensing the color of articles wherein a first pair of wavelengths is selected on a plurality of light reflection curves in terms of reflected light wavelength spectrum, these curves being associated with a plurality of articles constituting a sample representative of the color range to be sensed. The first pair of wavelengths delimits a first range of wavelengths corresponding to light reflection values in these curves, the light reflection values in each of the curves being in a substantially linear relationship over said first range of wavelengths. Each article to be inspected is illuminated with light comprising the first pair of wavelengths, and the light reflected therefrom is measured to detect light reflection values corresponding to the first pair of wavelengths.  A primary signal is produced which represents either a difference between or a ratio of said detected light reflection values, this signal being indicative of the color of the inspected article.

Title: Television signal transmission and reception system with multi-screen display for tuning operation
Inventor: SHIGIHARA HIDEO
IPC: H04N5/44
Filed: 1993-11-04
Granted: 1999-12-21
Abstract: Television signal transmission and reception system includes a broadcasting center, a transmission network and many reception terminals. In the broadcasting center, plural television signals corresponding to individual channels are modulated into transmittable form, and a synthesis circuit synthesizes the television signals to produce a synthesis image signal for a multi-screen display comprising plural small screens. Both the ordinary television signal and the synthesis image signal is transmitted with control information to the reception terminals through the transmission network. In the reception terminal, for selecting a desired channel out of the individual channels, the synthesis image signal is used for displaying a multi-screen, a moveable cursor image is superimposed on the multi-screen for designating one small screen corresponding to the desired channel. The channel designated by the cursor image is detected based on the control information, and the television signal of the designated channel is demodulated.

Title: Power amplifier combining network
Inventor: SCHWENT DALE G
IPC: H04B1/04
Filed: 1993-01-11
Granted: 1999-09-07
Abstract: A dual-mode RF signal power amplifier combining network is comprised of two branches, each having a power amplifier (200 and 201). The first branch contains a non-linear mode power amplifier (200) while the second branch contains a linear mode power amplifier (201). The non-linear mode branch also has an RF switch (210).  Both branches are coupled to a common output node (220). The common node (220) is coupled to a filter ( l07) before going to an antenna ( 106). The non-linear mode power amplifier (200) operates when an FM signal is to be amplified, while the linear amplifier (201) is biased in an off state. The linear mode power amplifier (201) operates when a digital signal is to be amplified, while the non-linear amplifier (200) is biased in an off state. The RF switch (210) removes the non-linear amplifier (200) from the circuit to prevent loading the on state linear amplifier (201).

Title: Enclosure apparatus for protecting a person against outdoor exposure factors
Inventor: HINSHAW JAY M
IPC: A47G9/08
Filed: 1993-10-18
Granted: 1995-11-14
Abstract: A multi-functional enclosure device made of four layers of compliant thin sheet material has an interior bag, and a sur-rounding exterior bag that opens at the bottom.  Thermally insulative material can be inserted into the space between the two bags.  Closeable slits disposed mid length form a portal for insertion of a user's head, thereby permitting the device to be folded upon itself and worn in a poncho mode.  In other modes of use, the device can serve as a comforter or mattress, and a combined sleeping bag and bivouac shelter.  When free of insula-tive material, the device can be compacted to a very small storage state.

Abstract: A volumetric dry solids materials feeder comprises a supply hopper (12), a feed trough (26) disposed below the hopper, and an auger (28) disposed in the feed trough (26) to feed out the material. The trough (26) is anchored to a vibration base (32), on which is mounted a vibratory mechanism (56). A vibration transfer spring (36) connects the vibration base (32) to a bracket (38) secured to the hopper (12).   Upon activation, the vibratory mechanism (56) vibrates the vibration base (32) and thus, the trough (26) at a predetermined frequency, while the spring (36) transfers the vibration to the hopper (12). The spring (36) lessens the amplitude of the transferred vibration and changes the frequency thereof, so as to minimize interference (primarily harmonic problems) between the vibration of the hopper (12) and trough (26).

Abstract: An ophthalmic lens pallet is provided having wells for receiving one or more lens containers at the receiving point. The pallet achieves the requisite uniformity of motion needed in the direction of motion and stability when transporting the lens in the orthogonal, non-translating directions by restraining the pallet between rails. Mechanical bias means such as a spring-loaded roller ball located on the side walls of the pallet body cooperate with guide rails on the conveyor to compress the mechanical bias means when the pallet is between the guide rails. Engagement means on the pallet engage a drive means which transports the pallet from the lens receiving point to an inspection station then to a lens disposition mechanism. The pallet wells comprise holes that pass through the pallet. These holes along with the rail and transport system make possible an arrangement of a lamp and camera for capturing an image of a lens.

Title: Plasma arc torch with integral gas exchange
Inventor: CARKHUFF DONALD WESLEY
IPC: H05H1/34
Filed: 1994-10-03
Granted: 1999-01-19
Abstract: A plasma arc torch for minimizing delay in exchanging gases within the torch.  The torch includes a metallic electrode, a conductive nozzle spaced apart from the electrode, and a gas plenum between the electrode and nozzle.  Two gas passageways are provided for communicating non-oxidizing and oxidizing gases into the plenum.  A plenum inlet check valve is associated with each gas passageway and is located in close proximity to the plenum.  The check valves are normally biased in a closed position but may be opened by gas pressure within the passageways to selectively introduce gas into the plenum.  Solenoid valves located upstream of the plenum check valves regulate the pressure and flow of gas within the passageways so as to open and close the plenum check valves.  Pilot arc and main arc power supplies are provided for generating an arc between the electrode and nozzle while the non-oxidizing gas flows through the plenum and for transferring the arc and sustaining it between the electrode and workpiece when oxidizing gas is introduced into the plenum.  Operation of the check valves and power supplies is coordinated so that the oxidizing and non-oxidizing gases are exchanged substantially simultaneously with transfer or termination of the arc.

Granted: 2000-02-15
Abstract: An apparatus and method is described for multicasting an inlet data cell, received (SOI) as part of a multicast request, through a self-routing multistage routing network by decomposing (504, 514, 524) the multicast request into one ormore intermediate multicast requests, each intermediate multicast request being a unique subset of the original multicast request which enables a non-blocking, self-routing distribution to a subset of the desired outlets of the original multicast request in one or two passes through the network, and by generating (505, 515, 525) a non-blocking multicast tree based on the intermediate multicast requests and routing the received inlet data cell to the desired outlets. The invention decomposes the original multicast request and generates a non-blocking multicast tree using a cube routing algorithm, a copy routing algorithm, or a combined routing algorithm, which is a combination of the copy and cube routing algorithms.
