Abstract: A heat containment apparatus may include a housing having an access gap, the housing being formed of an insulating material. Alternatively, a heat containment apparatus includes a housing being an expandable structure having an access gap, the housing including an insulating material. Heat containment apparatuses may be used in conjunction with performing high temperature operations and/or low temperature operations to at least portions of substrates contained therein.

Abstract: A heat containment apparatus may include a housing having an access window, the housing being formed, at least in part, of an insulating material. Alternatively, a heat containment apparatus includes a housing being an expandable structure having an access window, the housing including an insulating material. Heat containment apparatuses may be used in conjunction with performing high temperature operations and/or low temperature operations to at least portions of substrates contained therein.

Abstract: A hand-held exercise apparatus is provided. The hand-held exercise apparatus includes a body portion having a bar to allow a user to grip the apparatus, and a housing portion configured to sit atop of the body portion to receive a weight portion, wherein the weight portion is removable.

Abstract: An apparatus for sensing the integrity of an antenna which is located within a wristband and which is coupled to a wrist worn communication device having a receiver, and an antenna sensing circuit which generates an antenna sensing signal. The antenna sensing circuit monitors the antenna sensing signal and derives an antenna integrity indication signal which indicates the integrity of the antenna. An indicating circuit is responsive to the antenna integrity indication signal and provides a sensible indication of the integrity of the antenna, such as a message indicating the antenna is open.

Abstract: A selective call receiver and carrying case both include a surface for interchangeably attaching a mounting clip assembly to the selective call receiver housing and the selective call receiver carrying case at the discretion of the user.

Abstract: A paging system which provides both individual and information services includes a transmitter which transmits page call address and data periodically in batches to subscribing paging receivers. Each batch comprising a synchronization code followed by a predetermined plurality of sequential frames. Each paging receiver searches for both its individual service address and a first information service address in its corresponding assigned frame of each batch of a transmission period, and in response to reception of the first information service address, searches for a second information service address in a designated common frame of each batch of a transmission period. Individual and information service data messages are obtained from frames immediately subsequent the frame in which the respective individual and second information service addresses are found.

Abstract: A paging system which provides both individual and information services includes a transmitter for transmitting page call address and data periodically in batches, and a population of battery saver paging receivers for receiving the transmitted call information. Each transmission batch comprises a synchronization code followed by a predetermined plurality of sequential frames. Each subscribing receiver searches for its individual service address in a first designated frame of each batch of a transmission period, and in addition, searches for its information service address in a second designated frame of a designated batch of a transmission period. Individual and information service data messages are obtained from frames subsequent the frame at which their respective address is found.

Abstract: A display device has a single switch that transfers a stored message to a liquid crystal display and simultaneously activates a supplemental display lighting system. The supplemental lighting system is inhibited, however, when circuitry senses that ambient light conditions are sufficient to illuminate the display.
