Title: Apparatus for determining battery pack temperature and identity
Inventor: TRINH DANH T
IPC: H01M10/44
Filed: 1999-06-03
Granted: 2008-11-18
Abstract: A battery monitor system that determines battery pack temperature and battery pack identification. The battery pack includes a battery pack circuit having a thermistor and an AC circuit component. The battery monitoring system determines the battery pack temperature by measuring the resistance of the thermistor when the battery pack circuit is in a steady-state condition, and determines the value of the AC component based on a changing or dynamic electrical condition of the battery pack circuit. In one embodiment, to determine battery pack identification, an identification capacitor is connected in circuit with the thermistor. One terminal of a comparator is switched to a low reference voltage potential once the identification capacitor has been charged, and the output of the comparator gives an indication of the discharge rate of the capacitor, and thus its identification. In an alternate embodiment, the battery monitor circuit determines the identity of the battery pack by determining whether a thermistor does or doesn't exist, and if so, whether an identification capacitor does or doesn't exist.

Patent CA-2294540-C (CA)
Inventor: ARFELE ROBERT W
IPC: E21B10/61
Filed: 1998-05-29
Granted: 2007-01-23
Abstract: A fluid nozzle (11) for threaded insertion into a drill bit (10).      The nozzle (11) is equipped with a drive head (21) that receives a socket-type torquing tool (25). The torque forces exerted by the tool compress the drive head, permitting larger torque forces to be exerted on the nozzle. Use of a compressive drive structure permits the use of less material, which in turn permits a larger flow passage to be formed through the nozzle for a given nozzle size. The facets (22, 23 and 24) of the drive area may be inclined relative to the nozzle axis to limit the torque force applied by a drive tool. When the torque force exceeds a limit determined by the configuration and inclination of the facets, the tool is forced axially off of the drive area.

Title: Resource interface unit for telecommunications switching node
Inventor: NOONAN MICHAEL E
IPC: H04Q3/00
Filed: 1999-06-03
Granted: 2009-12-22
Abstract: A telecommunications switching node that includes at least one resource interface card (108) which serves as an interface for connection to external call processing resources (336). The interface card communicates with the line cards in the switching node directly over the system buses (118, 120, 122, 124), i.e. without passing through the CPU/matrix card (104) and it uses two line card ports to connect to all external resources. The resource interface card (108) also communicates with line cards (106) that are connected to the system buses in other switching nodes in an expanded switching network. Its resources are thus available to ports in the other nodes when those nodes have available ports that are not occupied with other tasks. For communications with the latter ports, the resource interface card (108) transmits information through the CPU/matrix cards (104) on its switching node and on the nodes where the communicating ports reside. Thus for communications with ports on its switching node, the interface card (108) receives information on the incoming bus (340) and transmits it on the outgoing bus (342) and for communications with ports on other nodes it receives information on the outgoing bus (342) and transmits it on the incoming bus (340).

The cutting tool is advanced on a path which curves toward the central axis of the lathe. A curved support member of the same curvature as the cutting tool is rotatable about a support post and is positionable below the cutting tool.
