Title: Programmable automatic prefix dialer for wireless telephone
Inventor: NELSON ROBERT M
IPC: H04Q7/32
Filed: 2002-04-09
Abstract: A method, and apparatus for practicing the method, for eliminating the necessity for manually dialing, on a wireless telephone, a local area code as a prefix to a call within the same area code in telephone systems in which such action is a requirement. Before a calling party institutes a call on a cellular telephone, the area code is semi-permanently stored in the cellular telephone. During the dialing process, after the seventh digit has been dialed and before an eighth digit has been dialed, a determination is made as to whether the "send" button has been actuated. If so, then the stored area code is prefixed to the seven dialed digits, and the resulting ten digit number is transmitted. If not, then the dialing continues until the "send" button is actuated at which time the fully dialed number is transmitted. Typically, the latter condition indicates that a long distance call is in process. Thus, in a preferred embodiment, a determination is made that eleven digits have been dialed, and those eleven digits are transmitted. Because a cellular telephone is portable by nature, provision is made to update the automatically-prefixed area code when the cellular telephone is moved to a different area code.

Title: Edible fat-based discrete flavoring additive with anhydrous dextrose and optional fructose component
Inventor: MILLER VLADIMIR
IPC: A23L33/00
Filed: 2002-05-13
Abstract: An edible anhydrous fat-based discrete flavoring additive may be provided in the form of chips, flakes, or chunks. It comprises less than 2% by weight of moisture; from 2% to 10% by weight of anhydrous dextrose; from 0% to 15% by weight of crystalline fructose; from 5% to 15% by weight of finely ground or liquid natural flavoring agent; from 25% to 35% by weight of an edible oil having a melting point between 20°C and 40°C; with the balance being finely ground sugar. The flavoring may be cinnamon or other natural ingredients such as maple, vanilla, almond oil, and botanical flavors. The presence of the anhydrous dextrose, which is hydrophilic, assures that the fat-based discrete flavoring additive is, itself, anhydrous; it also may contribute a slightly sweet aftertaste. The presence of crystalline fructose, when used, contributes a crunchiness to the anhydrous fat-based discrete flavoring additive.

Abstract: The currently available Personal Flotation Devices (PFD's) commonly include a chest harness and shoulder straps which can be used for rope attachment for underwater entrapment extraction purposes. This invention utilizes a load bearing waist harness in conjunction with the standard chest harness. The shoulder straps extend via a sleeve to the chest and waist harnesses such that any load applied to the shoulders will be transferred to these harnesses with an equal distribution of force. This greatly decreases the chance that the PFD will be pulled off the victim in an entrapment rescue situation.

Title: An asset and personnel tagging system utilizing gps
Inventor: WERB JAY
IPC: G01S5/14
Filed: 2000-05-04
Abstract: A system for tracking objects outdoors. Tags (202) attached to objects such as trailers include GPS receivers (203). Tags transmit uncorrected position and satellite data to a base station (205), where differential corrections are applied, providing 2-5 meter accuracy of the position of the tag and object.  Tags are on a low duty cycle. When a tag powers on, it receives accurate time and current satellite data from the base station, enabling the tags to acquire the satellite signal quickly and with minimum power consumption. When a tag is out of base station range, the tag periodically calculates and archives its position. The tag may also include Real Time Locating Systems technology, to enable tracking to continue when the tag moves indoors and becomes inacessible to GPS satellite signals.

Title: Wood composite panels for disaster-resistant construction
Inventor: DAGHER HABIB J
IPC: B32B5/14
Filed: 2001-02-21
Abstract: A wood sheathing panel, suitable for use in building construction, includes reinforcement strips of fiber reinforced polymer material incorporated into the panel. The reinforcement strips cover an area that is within the range of from about 5 to about 50 percent of the surface area of the panel. The reinforcement strips of fiber reinforced plastic material can be incorporated in the perimeter of the panel, or can be incorporated into the corners of the panel. The spacing of the intermittently incorporated reinforcement strips can generally coincide with a standard spacing of framing members so that when the wood sheathing panel is applied to a building frame, the reinforcement strips are generally aligned with framing members of the building. Preferably, the reinforcement strips are sufficient to provide an increased ductility over an equivalent unreinforced wood sheathing panel in an amount within the range of from about 75 percent to about 500 percent. A  plurality of the wood sheathing panels of the invention can be assembled together in building construction (10) as one element of a group consisting essentially of shear walls (12, 14, 24, 26), horizontal diaphragms (20, 22) and roof diaphragms (28).

IPC: G01S7/00
Filed: 2001-04-13
Abstract: A method and apparatus for determining whether cargo is present in a freight car. The freight car has a proximal ("rear") end with a loading door and opposing, distal ("front") end. One or more transmitters and receivers are mounted inside the freight car at the front end, toward the car's ceiling. The transmitters/receivers are operated by a controller, which also functions to analyze data from the transmitters/receivers and transmit related reports to a remote monitoring site. During a prescribed time period, a transmitter generates an ultrasonic signal pattern with a coverage area of prescribed radius that terminates before reaching the loading door. During the time period of transmission, or slightly later to account for signal reflection time, the controller operates the receiver to detect reflected signals originating from the transmitter. Then, the controller transmits a report of whether cargo is present in the freight car, based on whether any reflected signals were received.
