Title: Gps power/data cable system
Inventor: WOOD CRAIG S
IPC: H01R31/00
Filed: 1997-09-16
Abstract: A device for coupling global positioning system (GPS) receivers (2) to computer systems (1) in a way that takes advantage of available power supplies. The device includes an adaptive power base (15) that may be used to replace the standard battery-pack bases (6) of many GPS receivers. The adaptive power base (15) is coupled through an interface cabling system to an external power supply. The power supply may be associated with the computer (1) means, such as a mouse or keyboard port (5), or it may be a completely separate source, such as an automobile's cigarette lighter outlet (12). The interface cabling system includes coupling for linking the data communications ports (2, 3, 4, 5) of the GPS receiver and the computer system together. Through the design of the present invention, the GPS (5) receiver is more adaptive to available power sources and therefore may be used for longer periods of time and in a variety of locations. The design is simple in that it includes standard connectors (205, 215).

Abstract: A system is herein provided comprising mechanisms (114, 100, 110, 106, 107, 108, 200, 300) and methods of defining, creating, operating, and testing virtual robots ("BOT") (404). A virtual robot (404) as provided herein encompasses categories (510, 520, 530, 540, 550) and topics (710, 720, 730, 740, 750, 402, 820, 830, 840, 630) of natural conversation that can be encoded in a natural "script language" (108, 118, 120). During the course of operation, these categories (510, 520, 530, 540, 550) are activated according to the conversation (900 - 3002) taking place with a user. Different categories (510, 520, 530, 540, 550) are focused at different times according to changes in the conversation (900 - 3002). The system provides both automatic and explicit mechanisms (114, 100, 110, 106, 107, 108, 200, 300) for focusing categories (510, 520, 530, 540, 550) and topics (710, 720, 730, 740, 750, 402, 820, 830, 840, 630) during the course of conversation (900 - 3002). Additionally, if more than one category (510, 520, 530, 540, 550) seems appropriate to answer a particular user statement, the system provides mechanisms (114, 100, 110, 106, 107, 108, 200, 300) for selecting the most appropriate response (900 - 3002). Similarly, the system provides mechanisms (114, 100, 110, 106, 107, 108, 200, 300) for verifying the accuracy and appropriateness of the virtual robot's response (900 - 3002) by encoding test examples into the virtual robot script (108, 118, 120).
Patent CA-2292714-A1 (CA)
Title: Constant current power supply over a wide range of input voltages
Inventor: LOMBARDI ALFRED J
IPC: H02M7/06
Filed: 1999-12-20
Abstract: Two transistors are arranged as a Darlington amplifier to produce a constant current through an output resistor coupled to the emitter of the second transistor. AC power is supplied to a full wave bridge which converts the AC power from the source to a DC signal. A first zener diode and the base to emitter voltage drops of the transistors control the voltage across the output resistor. As the input voltage to the bridge is increased above the voltage between the emitter of the second transistor and ground, the extra voltage will be dropped across the collector to emitter of the second transistor. The same current will flow through the output resistor regardless of any input voltage in a defined range. By adding a resistor and diode and detecting the voltage between the resistor and diode with respect to the circuit the zero crossings can be detected.

Title: Tamper-indicating closure
Inventor: WILDE SHELDON L
IPC: B65D55/02
Filed: 1998-12-17
Abstract: A tamper-indicating closure (20) for a container includes a cap (24) having a top wall (26) with removable panels (34). Each removable panel (34) is connected to a tab (36) on the inside of the cap. The top wall includes inner and outer cams (42, 44) on an inside surface and the tabs underlie the cams. A liner disc (32) is applied inside the cap for sealing against the container. A plurality of spaced-apart ratchet teeth (66) are arranged in one or two circular patterns on the disc such that the teeth mesh with the two cams. The tabs (36) have a toothed transverse cross-section which allow the tabs to ride over the ratchet teeth (66) when screewing-on the cap, but are engaged by the teeth when screwing-off.  Since the liner disc (32) and ratchet teeth (66) are stationary with respect to the container, unscrewing of the cap (24) causes the ratchet teeth to separate the panels (34).
