Abstract: The privacy product—used with an information system which has a data processor (71) signal connected (72) to a display device (81) and has an input device (51, 51A) signal connected (52, 52A) to the data processor with the input device being manipulated (21) by a person to control cursor motions—comprises a computer readable signal bearing medium (11) signal connected (14) to the data processor with the medium having a chaff component (12) which causes the data processor to cause the display device to display (82) a chaff path (31A) which is indistinguishable from the cursor path (31) by a sequent person.

Abstract: An imager (11) has a locate mode (13) which detects light (31A, 31B) having a preset light property from at least one locator (21) in the imager field of view (12); and has a react mode which is caused by the locate mode to select light from a code region (22, 32A, 32B, 33B) over light not from the code region (81) and which outputs a signal (41) representing code in the code region.

Abstract: A thermometer implant (10), especially useful in medical diagnostic and therapeutic procedures, comprises a thermometer body (15) containing a fluid (13) which expands, and contracts to a fluid length (14) that indicates a target temperature at a target time, and which is located in a body from where the expanding fluid is not visible at the target time, with the fluid length (14) at the target time being measured outside the body.

Abstract: The product comprises an imager (21), a coded data source (11), and a variable property having a first use, with light emanating from the coded data source (11) representing the first use and specifying which portion of light detected (12) by the imager (21) represents the variable property, where the coded data source (11) can be from a plurality of coded data sources and the imager (11) can be from a plurality of imagers (21).
