Diversity receiver for wireless applications. In some embodiments, a receiver system can include a controller configured to selectively activate one or more of a plurality of paths between an input and an output, and a plurality of amplifiers, with each one of the plurality of amplifiers disposed along a corresponding one of the plurality of paths and configured to amplify a signal received at the amplifier. The receiving system can further include two or more of features including (a) variable-gain amplifiers, (b) phase-shifting components, (c) impedance matching components, (d) post-amplifier filters, (e) a switching network, and (f) flexible band routing. In some embodiments, such a receiving system can be implemented as a diversity receive module.

A beverage containing radio assembly combining a radio with a beverage container includes a container that selectively contains a beverage. The container is comprised of a thermally insulating material to inhibit heat exchange between the beverage and ambient air. A lid is removably coupled to the container and the lid retains the beverage within the container. A radio unit is coupled to the lid and the radio unit is configured to be in electrical communication with an extrinsic communication network. Thus, the radio unit emits audio received from a selected radio station.

Tablet PC (10) includes communication units (11.sub.1, 11.sub.2), antenna terminal (T.sub.1) used to receive one of first and second signals, antenna terminal (T.sub.2) used to receive another one of the first and second signals, terminal switch (40) configured to perform switching between a first coupling state in which communication unit (11.sub.1) and terminal (T.sub.1) are coupled, and communication unit (11.sub.2) and terminal (T.sub.2) are coupled, and a second coupling state in which communication unit (11.sub.1) and terminal (T.sub.2) are coupled, and communication unit (11.sub.2) and terminal (T.sub.1) are coupled, and controller (30) configured to control terminal switch (40) so as to switch to the first coupling state when terminal (T.sub.1) receives the first signal, and terminal (T.sub.2) receives the second signal, and to control terminal switch (40) so as to switch to the second coupling state when terminal (T.sub.1) receives the second signal, and terminal (T.sub.2) receives the first signal.

A portable loudspeaker includes an enclosure that defines an acoustic cavity. An electro-acoustic transducer is disposed within the acoustic cavity. A strap is provided which has a first end that is fixedly coupled to the enclosure and a second end that is releasably coupled to the enclosure. The second end of the strap is configured to be coupled to the enclosure (e.g., to secure an object therebetween). The second end of the strap is also configured be coupled to another portion of the strap to form a closed loop.

The present disclosure relates to the field of safety and warning devices, such as a system for zone entry warning. The present disclosure utilizes attaching a stretchable band to the worker enabling the warning of the worker that they are proximate a demarcated zone.

Disclosed herein, among other things, are systems and methods for managing power consumption in a wireless network. One aspect of the present subject matter includes a method for wireless communications of isochronous data. A transmission of isochronous data is received using an electronic device having a battery. The method determines how many redundant transmissions can be received by the device within a predetermined time frame while limiting discharge of the battery, and adjusts reception of the redundant transmissions based on the determination. In various embodiments, a reduction in received redundant transmissions preserves energy and prevents complete discharge of the battery.

In some embodiments, techniques are provided for extending the functionality of a receiving unit which is configured to express a state during an event. In some embodiments, a receiving unit configured to receive a first set of transmissions during an event from one or more transmitting units and express a state in response may also be configured to receive a second set of transmissions from other components at a time other than during the event and express a state in response to receiving the second set of transmissions.

A covert sports communication system has a transmitter configured to wirelessly transmit coded audio track selection signals. The system includes a receiver that may be worn within headgear. The receiver includes stored audio tracks and is configured to receive coded audio track selection signals from the transmitter, decode the audio track selection signals, and play at least one stored audio track in accordance with the decoded audio track selection signals. The audio tracks may include audio instructions to a participant of a sporting event.
