摘要： A system for recognizing an auxiliary display attached to an electronic price label which also recognizes a unique type designation of the auxiliary display. The system includes a number of auxiliary display recorders which sense a number of indicators on the auxiliary display. The indicators are arranged in a predetermined pattern which uniquely identifies a type designation for the auxiliary display. The system also includes an auxiliary display sensing circuit coupled to the auxiliary display recorders which determines the type designation of the auxiliary display from the pattern.

摘要： A mixing apparatus includes a Gilbert cell connected to a first load and a second load. In one embodiment each load contains transistors that are configured as a diode and a triode, where these circuits are additively combined to achieve substantially linear voltage-current characteristics over a predetermined range. The mixing apparatus takes two pairs of differential inputs and produces a pair of differential outputs. Because of the substantial linearity of the loads, the inputs and outputs of the mixing apparatus are acceptable over a relatively large range of input settings. In other embodiments each load may contain a transistor configured as a triode and a resistor, where these circuits are likewise additively combined to achieve substantially linear voltage-current characteristics over a predetermined range.

摘要： A remote control device and method for electronic price label (EPL) systems which includes circuitry from EPLs. The remote control device includes a first EPL circuit, a second EPL circuit, and a control circuit coupled between the first and second EPL circuits for enabling transmission of alternating signals to the EPL computer by the first and second EPL circuits. The EPL computer executes a function in response to the alternating signals.

摘要： A system and method of controlling an electronic price label (EPL) through infra-red signals instead of push-button signals. The system includes a computer which transmits wireless radio frequency messages containing functions codes and instructions, and a portable terminal which emits infra-red signals containing at least one of the function codes. The EPL receives the radio frequency messages, stores the function codes and corresponding instructions in a memory within the EPL, receives the infra-red signals from the portable terminal, determines the instructions associated with the function codes received from the portable terminal, and executes the determined instructions.

摘要： A system for managing multimedia objects such as text, images, sound, and video clips. The system provides improved organization of multimedia objects, through use of albums organized into collections of albums. In addition, improved printout of multimedia objects through user-activateable selection of particular fields from a multimedia database to accompany printouts of multimedia objects. A user interface is defined for allowing a user to obtain a thumbnail view of images in multimedia objects, simply by sliding a mouse cursor over database entry pointing of the image. In addition, a unique architecture of a system for managing multimedia objects is described.
