Abstract: An alarm extension device includes a retainer configured to receive a personal paging device, a vibration sensor in operative association with the retainer, an auxiliary alarm generator, and a link between the vibration sensor and the auxiliary alarm generator. The link is sufficient to activate the auxiliary alarm generator when the vibration sensor identifies vibration from the retainer. An alarm system includes at least one wireless alarm transmitter. The transmitter is configured to receive a prompt by a hazard condition detector to send a paging code in a manner recognizable by multiple personal paging devices without requiring identification of individual personal paging devices. The transmitter is also configured to send the paging code addressing multiple personal paging devices collectively, without regard to such devices individually, and including a hazard condition alarm message.

Abstract: An alarm system includes at least one wireless alarm transmitter, at least one wireless activate transmitter, and at least one wireless signal receiver. The signal receiver becomes sensitized to recognize an alarm code from the alarm transmitter after recognizing an activate code from the activate transmitter. The signal receiver can include an alarm generator that provides a first alarm after recognizing the alarm code. An alarm device can include a wireless hazard signal receiver that becomes sensitized to recognize a wireless transmitted hazard alarm code only after recognizing a wireless transmitted activate code. An alarm generator can provide a hazard alarm after recognizing the alarm code. The device can further include an alarm code and activate code decryption device. Instead of or in addition to the activate transmitter and sensitizing feature, the system can be equipped to display a location name in the alarm generator as a text alarm.

Abstract: A lighted writing support may include an apparatus having a portable writing surface, a light assembly linked to the apparatus, and a switch for directing electrical power with the light assembly. The portable writing surface may comprise a handheld writing surface. The light assembly comprises a light source adapted to selectively emit when powered a first spectrum of light or a second spectrum of light different in a visible portion of the spectra from the first spectrum. A housing partially surrounding the light source may direct emitted light over the writing surface. The light source may comprise a first-type of light emitting diode (LED) to emit a first color of light and a second-type of LED to emit a second color of light. The first color may comprise light approximately red in appearance and the second color may comprise light approximately white in appearance. The light assembly may include a clamping surface biased against the writing surface to retain papers, documents, etc.
