Granted: 1998-11-24
Abstract: In a method of recognizing an input pattern represented by a time sequence of input feature vectors (a(t)) as a recognized pattern selected from a plurality of reference patterns which represent categories of recognition objects, respectively, each of the reference patterns is defined by a sequence of state models, successively supplied with the time sequence of the input feature vectors and with a sequence of preceding state vectors (h(t, s, n)), the sequence of the state models produces a time sequence of predicted feature vectors (A(t+l, s, n)) and a sequence of new state vectors (h(t+l, s, n)).  The recognized pattern is selected from one of the reference patterns that minimizes a prediction error between the time sequence of the input feature vectors and the time sequence of the predicted feature vectors.  The prediction error is calculated by using a dynamic programming algorithm.          Training of the reference pattern is carried out by a gradient descent method such as back-propagation technique.

The control circuitry (40)  allows for manual adjustment of the sensitivity of the sensors (66).    The  circuitry  in  the  sensors  (66)  is minimized to only the transmitter, receiver and amplifier.     Furthermore,  each  bag  (18)   is controlled by separate control circuitry (40)  so that failure of one air bag and associated circuit does not effect any other bag's operation.

Abstract: The lid has a pair of radially-mounted jaws connected to a central actuating mechanism by a pair of transverse drive rods. A mobile control member (56) is located centrally on a control knob (50), for reciprocating movement in a direction radial to the knob and the lid.   Manual pressure moves the control member radially inwards, actuating the drive rods via a mechanical connection to move in a radially outward locking direction. The control member is linked to a control button (52), such that manual downward pressure on the button causes the control member to move radially outwards and the drive rods to move in a radially inward unlocking direction. The control member and button together form a central gripping handle for the lid. <IMAGE>

Granted: 2001-02-13
Abstract: An extendable lifting apparatus for a vehicle. The apparatus includes a support bracket secured to the floor of the vehicle.  A tube is mounted to the support bracket perpendicularly to the axis of the vehicle frame.  The tube receives a boom which is used to support a cable used to lift heavy objects.  The tube is substantially rectangular and has an axial slot extending along the bottom to form an axial opening that allows the cable to be suspended therein when the boom is in the fully retracted position.  The slotted wall of the tube also acts as a floor opposite an inner ceiling. A winch is coupled to the boom for successively winding and unwinding the cable.  A motor is coupled to the tube for moving the boom from a retracted position wholly within the tube to an advanced position.  A second motor is coupled to the winch for controlling the winding and unwinding of the cable.  Control of the two motors is provided by a remote control.  Finally, a brake is provided for preventing the unwinding of the winch allowing a suspended object to freefall when the second motor experiences failure.

Filed: 1995-10-30
Granted: 1999-07-27
Abstract: A needle point barrier includes a resiliently deflectable spring arm, a link arm and a barrier arm. The proximal end of the spring arm is secured near the proximal end of the needle. The link arm has one end hingedly connected to the spring arm and an opposed end hingedly connected to a proximal position on the barrier arm. Distal portions of the barrier arm slidably engage the needle. The needle point barrier can be collapsed into a Z-shaped configuration near the proximal end of the needle. The barrier arm can be urged distally by force applied to the proximal end of the barrier arm. Initial movement of the barrier arm willdeflect the spring arm away from the needle. After sufficient manual movement ofthe barrier arm, the resiliency of the spring arm will urge the barrier arm distally into shielding relationship with the distal end of the needle.

Abstract: A meat product and apparatus (2) and method of producing the same including a piece of meat which is heat treated to have no outer skin about its surface is disclosed. The meat is placed inside of an air-tight chamber (10) and steam generated from a source of water (12) is introduced into the cooking chamber  (10). The steam and pressure within the chamber (10) are regulated so as to create an atmospheric humidity of 100 % within the chamber, so any water present within the meat is prevented from evaporating into the atmosphere of  the chamber (10). The pressure may be reduced so as to produce a low temperature steam from 150 to 180 degrees F to cook the meat product. Additionally, a flavored ingredient, such as liquid smoke, may be added to t he water (12) to flavor the meat product and the pressure can be further reduce d so that a thin skin layer can be formed on the meat product surface.

Title: Dynamic learning of neighboring wireless cells
Inventor: CHAVEZ DAVID L JR
IPC: H04W36/08
Filed: 1997-11-12
Granted: 2002-02-05
Abstract: Using dynamic learning techniques by a system controller to determine a subset of neighboring cell sites to which an activity transfer should be attempted. An activity transfer can be a handoff or registration. The neighboring cell sites that should be chosen for an activity transfer are specified for each cell site. The specified neighboring cell sites are determined by the dynamic learning process. In a first embodiment, the dynamic learning is accomplished by accumulating statistical data that defines the average call duration of each of the selected neighboring sites after an activity transfer to each. Advantageously, this average duration can include the total call duration for two subsequent activity transfers. In a second embodiment, the dynamic learning is accomplished by accumulating statistical data that defines the maximum transmission power from the base station to which a handset was transferred. In a third embodiment, the duration of the low power transmission level of the base station from which the handset had just been transferred is timed. If the duration is less than a predefined number, it is assumed that a null had occurred, and that fact is stored for that cell. This information is used to detect multipath fading and to prevent premature handoffs when multipath fading occurs. Subsequently, a transfer is delayed for a cell having a large average number of nulls.
