Title: Tire changing apparatus
Inventor: BRUNNER LARRY F
IPC: B60B30/06
Filed: 1993-10-29
Granted: 2000-06-13
Abstract: This invention is a tire-changing device which is used for engaging then stripping the tire from rims of wheels. The device is used in combination with a workbench and stores under the bench when not in use. A threaded rod is raised above the bench top when the tire changer is in use. Mobility for the threaded rod is provided by having it slidably engage a sleeve which, in turn, is coupled to the bench. A friction pad is employed which rests on the bench and through which the threaded rod passes. A restraining hub through which the rod passes engages the hub of the wheel. A torque nut holds the hub firmly in place, thereby securing the wheel between the restraining hub and the friction pad. A double headed tool is provided which engages the rim of the tire. A first head is contoured to assist in engaging the bead of the tire to the rim and a second head is for the purpose of stripping the tire from the rim.

Granted: 1997-05-13
Abstract: An optical fiber light emitting apparatus (200) comprises at least one optical fiber (201) arranged in a repeating, recurrent pattern extending substantially throughout a predetermined area (206). The optical fiber (201) has a plurality of locations along the length thereof permitting light entering at least one end of the optical fiber (201) for transmission therein to be selectively emitted by the optical fiber (201) at the plurality of locations (210) for producing substantially uniform illumination substantially throughout the predetermined area (206). The repeating, recurrent pattern may form a spiral or serpentine pattern, for example. The repeating, recurrent pattern eliminates the space required for the fan-in arrangement (115) of prior art optical fiber light emitting panels (100). The optical fiber light emitting apparatus (200) is beneficial for illuminating keypads (613) and displays (611) in electronic devices (600), such as portable radio telephones, having limited space available.

Title: Fast connection setup interfaces using pre-assigned virtual channel identifiers
Inventor: SUZUKI HIROSHI
IPC: H04L12/70
Filed: 1994-05-26
Granted: 1999-09-28
Abstract: In a packet-switched network in which a source station dissembles a packet into multiple cells and transmits them in sequence to a destination station, each switching system pre-assigns a unique set of VCI to each outgoing line. Corresponding respectively to incoming lines, each switching system includes line interface units for receiving normal signaling cells, a fast signaling cell and a data cell. Each interface unit includes a memory for storing the VCIs pre-assigned to the outgoing lines and a header translation table for defining relationships between a set of incoming VCIs and a corresponding set of outgoing VCIs. The interface unit assigns one of the stored VCIs to the fast signaling cell according to its destination, establishes a connection in the translation table between an incoming VCI and the assigned outgoing VC, and assigns an outgoing VCI of the established connection to the data cell according to an incoming VCI contained in the data cell. A central controller is provided for assembling the normal signaling cells into a signaling packet and assigning one of the stored VCIs to each of the normal signaling cells comprising the signaling packet. A self-routing switch provides routing of any of the cells according to a VCI assigned thereto.

Patent CA-2137535-C (CA)
Title: Method for designating recorded messages
Inventor: RECHT THOMAS STUART
IPC: H04M1/725
Filed: 1994-12-07
Granted: 1998-07-14
Abstract: A method for designating messages allows individual messages to be designated as "read" if (i) the message has been played for a predetermined amount of time (150) or (ii) the replay of the message is completed (154). After a playback session, messages designated as "read" can be designated as "old" (102). Because of the queuing capability of the digital answering machine (142), stored messages can be replayed in any order, or a portion of a message can be conveniently replayed to determine whether the message should be replayed in full. As a result, new messages (i.e., messages which have not been designated as "read") can be located anywhere in the sequence of recorded messages. Such a function of the present invention allows a user to preview messages to selectively listen to messages, while maintaining a designation as "new" for any message in the sequence which has not been replayed in full or at least for a predetermined period of time. A user has the option of playing back all messages (92), or only those messages designated as "new" (98).

Abstract: An inverse transport processor system for a TDM packet signal TV receiver includes apparatus for selectively extracting desired payloads of program component data and coupling this data to a common buffer memory data input port. A microprocessor associated with the system also couples data to the common buffer memory data input port. The respective component payloads and data generated by the microprocessor are stored in respective blocks of the common buffer memory in response to associated memory address which are applied to a memory address input port by an address multiplexer. A decryption device is included to decrypt payload data according to packet specific decryption keys. In addition a detector is included to detect payloads including entitlement data. Payloads containing entitlement data are directed via the common buffer memory to a smart card which generates the packet specific decryption keys. A memory data output port is coupled to a bus interconnected with the respective program component processors. Responsive to data requests from the respective program component processors, and data write requests from the component payload source, memory access for read and write functions is arbitrated so that no incoming program data is lost, and all component processors are serviced.

Abstract: A buffer insert is emplaceable within a memory gauge system buffer chamber. The buffer insert includes a reduced diameter, extended inlet conduit that attaches to the buffer chamber opening. The inlet conduit employs capillary repulsion to impede entrance of wellbore fluid into the buffer chamber. The inlet conduit forces infiltrating fluids to enter proximate the top of the chamber rather than its bottom. The insert further includes an extended curled capillary allowing restricted fluid communication between the chamber and the transducer. Entrance to the curled capillary is located proximate the bottom of the buffer chamber, thereby forcing infiltrating fluids to travel downward through the more viscous silicon oil. Testing has shown the system of the present invention to greatly reduce contact with the transducer components by infiltrating wellbore fluids.

Abstract: This invention is an endometrial ablation device and a method of manufacturing and using the device. An RF current is passed through an endometrium (22) to heat it. An electro-conductive expandable member such as a balloon (10) is used as the medium for passing the current and causing the heating of the endometrium (22). The power delivered from a power source to the balloon (10) is selectively provided to a plurality of electrode area segments (34) on the balloon (10) with each of the segments (34) having a thermistor (32) associated with it whereby temperature is monitored and controlled by a feedback arrangement from the thermistors (32). The method of manufacturing the ablation device includes using commercially available stretchable sheet material or providing a mandrel (324) or support base (352) and coating the mandrel or base with an uncured emulsion. The emulsion is then cured to form a bladder-like coating, which is thereafter removed from the mandrel or base to form a bladder (320).

Abstract: Records stored in a database are reset on an as-accessed basis.  A record in the database to receive new data is identified when new data arrives to be incorporated with existing data in a given field. A next reset date stored in the record is read and compared with the current date.  If the current date is later than the next reset date, the existing data in the field is replaced with a predetermined default value prior to incorporating or incrementing the new data in the field. Additionally, another next reset date is calculated and substituted for the previous next reset date in the record.
