A system includes an asset management system in communication with an asset disposed within a rack, an asset tracking server, a gateway, and a set of equipment racks including the rack in which the asset is disposed. Each equipment rack defines a face. The equipment rack includes an observer device and a location indicator device. The system includes a set of tags attached to assets disposed within the set of equipment racks, a tag of the set of tags attached to the asset. The asset management system is to identify a maintenance event associated with the asset and is to communicate the identity of the asset to the asset tracking server. The asset tracking server is to locate the rack location of the tag associated with the asset and is to communicate with the associated observer device, which is to direct the location indicator device to provide a light signal.

A low voltage AC power controller uses a line coupled capacitor AC to DC converter circuit to obtain energy from AC line power supplied to an AC load and may be used with an external high voltage AC switching device to control power supplied to the AC load. The line coupled capacitor AC to DC converter circuit provides a low power device that senses characteristics of the power supplied to the load and can communicate sensed information and/or receive control information related to the power supplied to the load.

AC power controller

An integrated circuit includes a tuner, a digital television (DTV) demodulator, an analog television (ATV) demodulator, and a controller. The tuner includes an input for receiving a radio frequency (RF) signal including at least one of an analog television signal and digital television signal, and including a first output terminal and a second output terminal. The DTV demodulator includes a DTV input coupled to the first output terminal of the tuner and includes a DTV output terminal. The ATV demodulator includes an ATV input coupled to the second output terminal of the tuner and includes an ATV output terminal. The controller is coupled to the tuner, the DTV demodulator, and the ATV demodulator to configure the tuner and at least one of the DTV demodulator and the ATV demodulator for receiving television content in a selected television format.

Receiver and method of receiving analog and digital television signals

A transceiver includes a processor, which is adapted to in a transmit mode of the transceiver, form at least part of a transmitter and in a receive mode of the transceiver, form at least part of a receiver. The transceiver may include at least one analog-to-digital converter to provide digital signals to the processor in both the transmit and receive modes of operation; and the transceiver may include at least one digital-to-analog converter to receive digital signals from the processor in the transmit and receive modes of operation. The processor may be fabricated on an integrated circuit with at least one of the analog-to-digital converters and/or with at least one of the digital-to-analog converters.

Transceiver having multiple signal processing modes of operation

In one embodiment, a set of tracking filters to be coupled between an amplifier and a mixer is provided. The tracking filters may be differently configured depending on band of operation. For example, a first set of the filters can be configured to maintain a substantially constant Q value across their operating bandwidth while a second set of the filters can be configured to maintain a substantially constant bandwidth across their operating bandwidth.

In one implementation, a receiver may have an analog front end with an amplifier to receive a radio frequency (RF) signal and a mixer to downconvert the signal to a baseband signal. Then, a demodulator may receive the baseband signal and obtain an audio signal therefrom. Still further, a controller may be coupled to receive a control signal corresponding to a variable impedance level, and control a local oscillator coupled to the mixer responsive to the control signal. The variable impedance may be controlled by a user to tune to the channel.
