Abstract: The seal system is comprised of a custom integrated circuit utilizing a special CMOS gate-array technology that can be utilized to build inexpensive tamper-resistant electronic seals. The electronic circuit includes a special analog as well as digital, single-chip circuitry that senses the state of the seal, and when interrogated, transmits that state via a 35-bit data word to a seal reader device, allowing remote monitoring and control of containers and expensive goods. Any attempt to tamper with the seal will be recorded in the circuit for later transmittal to the hand-held seal reader/verifier. Each seal has a unique 20-bit identification number, combined with a 6-bit random seal code and a 6-bit resistance value. The seal electronics may be utilized in a way to provide several types of seals, namely, a shipping container seal, an event triggering seal, and event logging seal, and a tamper-proof seal as well as combinations thereof.

Abstract: A belted arthroscopic mobilizer is used to suspend a patient's leg from the waist of the surgeon or other user. The mobilizer allows the user to straighten, flex and otherwise manipulate the position of the patient's knee during arthroscopic surgery. The mobilizer has a shoe which craddles or cups the patient's foot. The shoe and an attached bracket are slidably coupled to a belt worn by the surgeon or other user.

Abstract: The candle has a wick that contains an optical guide, such as a fiber optic cable. An electronic circuit is coupled to the optical guide so that when an optical signal is received by the circuit, it plays a musical tune. For example, the optical guide can be coupled to an optical switch, so that the optical signal produced by the flame will close the switch and complete a circuit. The circuit can include a storage device, such as an IC CHIP, to store a musical tune. This tune is then played when the candle is lit. When the flame is extinguished, the burnt wick will prevent ambient light from activating the circuit.

Abstract: The pastry shield has a upper flange dimensioned to overlap the periphery of the pastry or pie being baked. The flange reflects heat away from the easily burned portions of the pastry. Further, the pastry shield can have cooling fins attached or integral therewith. These fins help pull heat in the shield away from the pastry. The fins also help after baking when the pastry is cooled. The pastry's pan can be set on top of the shield and the heat in the pastry and pan will tend to drain into the shield and be dissipated through the fins.
