Abstract: An all-inclusive, electronic digital business card with the capability to continuously receive updated and current information. The card includes such things as sales and other business updates, time, weather, website information which contemporaneously changes as circumstances change, current news, and different email addresses. The card has lettering, numbers, and pictures which light up. It contains photo images and has video and audio capabilities. There is no limit to what could be included on the card, including the ability to translate or change to different languages as needed.

Abstract: A portable electronic display device includes an electronic display surface having at least one display panel that displays a graphical and/or textual message, memory that stores a plurality of the messages, and one or more switches on the device that allow user selection of one of the messages. The device further includes a controller that disables the one or more switches if none of the switches are selected after a predetermined period of time after power is turned on to the display device, or if none of the switches are selected after a predetermined period of time subsequent to the last switch selection occurrence. In this manner, a person is prevented from subsequently changing the message via the one or more switches.

Abstract: A method and apparatus for locating an object. In one embodiment, the occurrence of a plurality of transitions between a first light level and a second light level is detected. If a time period between at least some of the transitions is determined to be less than a predetermined value, an alert signal is emitted. In another embodiment, the alert signal is emitted if an ambient light level is detected to be below a predetermined threshold and the object is detected to not be in a predetermined axial orientation.

Abstract: A method of balancing positive and negative ion output in an electrical ionizer having positive and negative ion emitters and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters includes automatically adjusting at least one of the positive and negative high voltage power supplies by ramping up or ramping down the at least one of the positive and negative power supplies at a predetermined rate. Another method of balancing positive and negative ion output in an electrical ionizer having positive and negative ion emitters and positive and negative high voltage power supplies associated with the respective positive and negative ion emitters includes automatically adjusting at least one of the positive and negative high voltage power supplies by ramping up the at least one of the positive and negative power supplies at a predetermined rate upon initiation of the operation of the electrical ionizer.

Abstract: A room ionization system includes a plurality of emitter modules, each including an electrical ionizer. The emitter modules are spaced around the room and are connected in a daisy-chain manner to a system controller. Each emitter module has an individual address for allowing the system controller or a remote control transmitter to individually address and control each emitter module. Electrical lines containing both power and communication lines connect the plurality of emitter modules with the system controller. Each emitter module stores a balance reference value and an ion output current reference value for use by automatic balance control and automatic ion output current control circuitry.

Abstract: Circuitry is provided in a device to automatically change the relative position of the electrical lines which enter the device upon detection of a miswired condition. More specifically, the circuitry allows the device to function normally even if an installer accidentally inverts (i.e., flips or reverses) the wiring connections when attaching connectors to a communication/power line of the device. In this manner, the installer does not need to rewire the lines.

Abstract: An indicator lamp indicates the status of an electrically-powered load control system by providing dim light when the load power is off and a brighter light when the load power is on. In another embodiment, the lamp not only provides two levels of light to indicate whether or not power is on, but also provides a repetitive flash when power to the system is being controlled by remote control. The indicator lamp can also indicate a break in the load circuit. Depending on the embodiment, the break can cause the lamp to be either off or flashing, regardless of the position of the load power switch. Alternatively, a break in the load circuit can cause the lamp to provide substantially no light if the load power switch is in the "off" position, with full light in the "on" position.
