In one embodiment each control consists of a bimetal supported in a spring metal carrier which has an integral part formed into a bistable, overcentre switch-operating mechanism. In another embodiment one control comprises a fusible component. Resetting of the or each bimetallic control is effected in response to lifting the appliance off its base and then reseating it on the base. The fusible component control holds the fusible component under spring tension so that when it melts in response to an overtemperature condition, the spring is released and causes rapid opening of a set of switch contacts. A steam sensor can be coupled directly to the connector.

Title: Usage based strength between related help topics and context based mapping thereof in a help information retrieval system
Inventor: WARNER DOUGLAS K
IPC: G06F17/30
Filed: 2001-04-05
Abstract: An information retrieval system allows a user to navigate through a plurality of informational items for a desired informational item, and upon selection of an information item, presents other informational items related to the selected informational item. The information retrieval system in accordance with the principles of the present invention maintains a database that defines a relational association between a plurality of informational items in the system. The relational association is based on historical navigational behavior of users of the information retrieval system, and includes a relationship type, which is based on the characteristic similarities between the informational items, and relationship strength, which is based on the historical frequency of any related informational items being selected by a user within the same information retrieval session. When a navigation from one informational item to another information item is detected, the relationship type and the relationship strength of the two informational items are determined and stored in the database. During a subsequent selection of an informational item, any related informational items related to the selected informational item are sorted based on the respective relationship types and relationship strengths, and are provided in a sorted list from which the user can select. In an aspect of the present invention, the inventive informational retrieval system is utilized in a help information retrieval system to provide a dynamic context sensitive mapping of help informational items. The inventive informational retrieval system in accordance with the principles of the present invention provides a convenient and economical retrieval of the one desired informational item while leveraging the investment of time and effort made during prior information retrieval sessions.

Title: Microprocessor instruction execution method for exploiting parallelism
Inventor: TAYLOR RICHARD MICHAEL
IPC: G06F9/38
Filed: 2003-06-30
Abstract: A mechanism for supporting speculative execution and code compression in a Very Long Instruction Word (VLIW) microprocessor using predication. Static- and dynamic-parallelism extraction is employed. A sequence of operations (instructions) are divided into individual strands (or blocks). Each strand is delineated by a branch operation and so each strand represents, in effect, a single branch. The processor executes code from a number of strands in parallel. Thus, the processor is able to execute instructions speculatively i.e., operations from different strands may be executed out-of-order with respect to their original sequential order, although operations within each individual strand are executed in sequential order. Each strand has an associated predication state that determines whether operations from the strand should be completed.

Title: Transfer of data messages during a telephone call
Inventor: FORD PETER J
IPC: H04M1/7243
Filed: 2003-11-22
Abstract: If a user wishes to send a data message (e.g. text message) during a telephone call, then the user must enter a text messaging application, write the message and then specify the address to which it should be sent. However, the user is likely to want to send the message to the other party in the telephone call. Therefore, the present invention describes a method for storing in a first terminal identifier data that identifies the second terminal. Then, when a data message is to be sent from the first terminal, the stored identifier data is used to automatically determine the destination address. An alternative embodiment automatically determines the destination address as the last caller. The data message can be an SMS or MMS message, calendar or contacts data, or video or image data.
