Abstract: A sign holder in the form of individual parts which, upon assembly, provides for the support and display of signage in a plurality of orientations. The sign holder includes a base configured to receive and support a first end to the stem, the stem having a first end and second end, the first end configured to be releasably retained by the base and the second end configured to retain a sign frame. The second end of the stem is provided with a C-shaped extremity sized to frictionally capture the sign frame such that the sign frame is releaseable from the stem by providing a lateral force to the frame.

Abstract: A transceiver for use in a wireless device. The transceiver may include a receive portion for receiving an input RF signal. The receive portion may include at least one receive filter which may include a first filter. The transceiver may also include a transmit portion for transmitting an output RF signal. The transmit portion may include at least one transmit filter, which may include the first filter used in the receive portion. The transceiver may further include a plurality of switches, which may include a first switch coupled to an input of the first filter and a second switch coupled to an output of the first filter. The plurality of switches may be configurable to enable use of the first filter in the receive portion for receiving the input RF signal and use of the first filter in the transmit portion for transmitting the output RF signal.

Abstract: A voltage controlled oscillator having a temperature and process controlled output. A VCO in accordance with the present invention comprises a reference current source, a fixed current source, coupled in series with the reference current source, the fixed current source comprising a temperature independent current source, a third current source, coupled in parallel with the combination of the reference current source and the fixed current source, and an oscillator, coupled in series with the third current source, wherein a current used to control the oscillator is based on operating temperatures and processes of the reference current source and the third current source.

Abstract: A collapsible megaphone device having a body portion capable of lying flat in a first state and capable of assuming the shape of a megaphone in a second state where in the first state, the collapsible megaphone device is substantially two dimensional and planar having a first edge, second edge and boundary edges joining the first and second edges. The collapsible megaphone device is convertible from the first state to the second state by exerting pressure against its boundary edges and is returnable to the first state by removing pressure from its boundary edges.

Abstract: A sign for the display of perishable goods in a display case. The sign includes a front face and rear face, the front face being visible to a consumer when in use providing information to the consumer regarding the perishable goods. The rear face has at least one rotating dial, individual or folded panel for selection of at least one date on which the perishable goods would be removed from the display case.

Abstract: A bracket device for removably securing a control box atop a portable amplifier. The portable amplifier is provided with a handle secured to its top by spaced apart securing hardware. The device is in the form of a resilient construct having a U-shaped top portion, a pair of bridging members emanating from the U-shaped top portion and a pair of extension members extending substantially perpendicularly from the bridging members and having free distal ends. The extension members are spaced apart from one another approximately the distance between the spaced apart securing hardware and is sufficiently resilient to enable the extension members to be drawn together a sufficient distance to enable its free distal ends to pass between the securing hardware and beneath the handle and to exert lateral pressure against the securing hardware to resist inadvertent removal of the bracket from the top of the amplifier.

Abstract: A collapsible pet enclosure in the form of a planar sheet material configured in the shape of a trapezoid. The planar sheet material is foldable along creases to create three subparts, each subpart being in the shape of a triangle. At least one of the triangular subparts is provided with an opening configured therein.
