Abstract: An anti-theft proximity alert system that includes a wearable smart charm with a charm housing having a button for the wearer to manually cancel a triggered sensory alert sequence. The object monitor may include within its housing a motion detector that monitors the state of motion of the object monitor, and at least one operating instruction that adjusts a property of the transmitted proximity signal in response to a change in the object monitor's motion state. A silent alarm of vibration and/or light on the charm housing perceptible to the wearer of the smart charm may be activated prior to the activation of an auditory alarm.

Abstract: An object proximity alert system using motion detection having a smart alarm component for receiving a proximity signal from an associated object monitor component. The object monitor includes within its housing a motion detector that monitors the state of motion of the object monitor, and at least one operating instruction that adjusts a property of the transmitted proximity signal in response to a change in the object monitor's motion state. The smart alarm sets off a perceptible alarm through one or more sensory alert mechanisms when the separation distance between the smart charm and object monitor is determined to exceed a threshold alert criterion.

Abstract: An anti-theft system that has a first component that is an attractive and light-weight smart charm that uses an accessory attachment device to attach to a wearable accessory such as a bracelet or necklace, an item of clothing, or user. The system has a second component that is an object monitor for attaching or combining with a mobile object, such as a wallet or purse. The smart charm and object monitor communicate proximity information between each other, and set off a perceptible alarm through one or more sensory alert mechanisms when the separation distance between the smart charm and object monitor exceeds a threshold alert criterion.

Abstract: An apparatus and a method for calibrating and normalizing a stereolithographic apparatus so that a reaction means directed by a positioning means supplied with positioning means information may be positioned accurately on a designated surface of a working medium. One or more sensors fixed in location with respect to the designated surface of the working medium are utilized to correlate positioning means information with specific locations on the designated surface of the working medium. Other locations intermediate the specific locations may then be determined by the technique of linear interpolation.
