Abstract: A switch interlock apparatus for use with switch panels that have pairs of functionally related switches, in which the handles for the switches are mounted in tandem and aligned with their pivot axes parallel to and spaced apart from one another, in which one of the switches must be flipped, before the other switch can be flipped. The switch interlock apparatus mechanically connects the handles of two functionally related switches so that as one switch moves from an "OFF" to an "ON" position, the interlock constrains the handle of the related paired switch to move from "ON" to "OFF" first. In a preferred embodiment, the switch interlock apparatus incorporates a monolithically formed interlock member that can be directly mounted to a switch panel without intermediate assembly steps.

Title: Candle with controlled wick placement
Inventor: KOTARY KARA L
IPC: C11C5/00
Filed: 2003-01-03
Abstract: The wick of a candle is anchored above the bottom of the candle a flame extinguishing distance so that the wick is extinguished by the candle's molten solid fuel when the wick is consumed. Placement of the wick in this manner helps to eliminate burn through. Additionally, a bottom cavity may be formed in the candle. The cavity may be used for the purpose of helping to anchor the wick a desired flame extinguishing distance above the bottom surface of the candle. The cavity may be advantageously filled with scrap wax material since it will not be consumed by the burning wick.

Title: Ad-hoc media delivery system
Inventor: STRIEMER BRYAN LESTER
IPC: H04L12/56
Filed: 2003-12-08
Abstract: Disclosed is an apparatus, method, and program product for performing ad hoc media delivery. Enhanced handheld devices are used in combination with the other components to route media and control its presentation. Enhanced media presentation stations detect the presence of one or more of the handheld devices. Information regarding the presence of a handheld device is then communicated from the media presentation stations to an enhanced server. The server uses this information to maintain a record of the location of each handheld device. The recorded location information is used to route the media to the media presentation station that is closest to the location of the handheld device. Control information, such as media selection and fidelity control (when appropriate), is forwarded from the handheld device to the server, so that the server can take appropriate action relative to transmission of the media to the media presentation station at issue. If a phone call is received, an enhanced phone interacts with the server to suspend presentation of the media until the phone call has ended.
