Abstract: Methods and apparatuses are disclosed to mold complex shapes using a cast mold technique. A catalyst-initiated urethane can be used for these complex shapes as there is little thickness restriction on any part dimension. Moreover, urethane, once chemically activated, can be poured into cast molds with various shapes. Due to the exothermic nature of urethane, when the curing chemical reaction takes place, metal molds can be fabricated from aluminum. Cast molds, made from aluminum, utilize elastomeric seals to account for coefficients of thermal expansion.

Abstract: Methods, systems, and data structures are provided for selectively securing data within a message. A single message includes data. The data can be text data, attachment data, audio data, image data, or video data. Portions of the data are selectively identified with intended recipients. Multiple versions of the message are produced using the selective portions of the data. Each appropriate version of the message is delivered to the intended recipients. In one embodiment, the selective portions of the data are presented as links in the versions of the message, such that when an intended recipient accesses the link, the accessing recipient is first authenticated before being granted access to the selective portions of the data.

Abstract: This invention allow a photographer to quickly and easily flip their on camera flash to a vertical position when taking a vertical photograph using a hinge that allows it to tilt to the left and right with wiring to transfer information between the flash and camera. The invention can be built into a flash or a separate device. This eliminates the need for a bracket and off camera flash cord cost, storage space in camera bag, and bulkiness when taking photos.

Abstract: A method for providing control commands to electronic equipment from a remote location comprises receiving a control command signal transmitted from a remote location The control command signal has a first carrier wave that includes a noise component. The method further comprises removing the first carrier wave from the control command signal, such that the noise component is also removed, thereby producing a TTL signal. The method further comprises generating a second carrier wave having a frequency substantially equal to the first carrier wave. The method further comprises applying the second carrier wave to the TTL signal to produce an output command signal.

Abstract: A retrofit bracket for wall mount speakers has a support surface configured for mounting at least one speaker thereto and a pair of elongate clamping bars extending across to opposite sides of the rear of the support surface and adjustably attach thereto such that a wall covering is clampably capturable intermediate the support surface and the bars. An adjustment means facilitates varying of the distance between the support surface and the bars to accommodate various wall covering thicknesses. The elongate bars are sufficiently flexible to provide spring tension against the wall covering captured intermediate the bars and the support surface. A foot is formed upon each end of the elongate bars for distributing the force applied by the bars over an increased surface area. The use of feet to spread the force of the bars over an increased surface area mitigates the potential for compression of the wall covering captured therebeneath.
