Abstract: A security system can be configured to mount to a power outlet. The security system can include an outwardly facing portion configured to face away from the power outlet and an inwardly facing portion having a first electrical prong and a second electrical prong that protrude into the power outlet to mount the security system to the power outlet. The security system can also include a detection system comprising a camera and a motion detector.

Abstract: Apparatus and methods are disclosed for selection of characters from an electronic user interface. In one embodiment, a letter selection interface displays letters in a row, some of which are recordable by an input interpreter and others that are unrecordable. In one embodiment, unrecordable letters visually separate letters that are both (1) recordable, and (2) assigned to different but adjacent selection buttons. In response to received touch-screen activations, an interpreter records recordable letter selections and a display displays both recordable and unrecordable letter selections. The interpreter composes a sequence of the recorded letters. An algorithm identifies alternatives to the recorded sequence by editing one or more letters of the sequence, such that each edit changes a selected letter to an adjacent unrecordable letter. The algorithm outputs words that match the originally composed sequence or one of the identified alternatives.
