Abstract: Furniture with a concealed compartment is provided. The furniture includes a tabletop and a base. Tracks on sides of the base mate with interior channels of the tabletop to enable the tabletop to be slid to reveal or conceal the compartment. The compartment may include a locking mechanism that prevents access to the compartment. The locking mechanism can be unlocked using a magnet.

Abstract: A cushion that converts into an ottoman includes a collapsible, hollow, rectangular container and a rigid, hollow, rectangular container including padding. The top of the collapsible container is open. The bottom of the rigid container is open, and a top and all sides of the rigid container are closed. The padding is disposed on the top of the rigid container. The collapsible container is configured to mate with the hollow portion of the rigid container when the collapsible container is collapsed to generate a cushion. The top of the collapsible container is configured to mate with the hollow portion of the rigid container when the ottoman is un-collapsed to generate an ottoman.

Abstract: A cap for illuminating a beverage container includes a lens, a light emitting diode (LED), a battery, a control circuit, a control button, and a transparent lower section. The LED is mounted between a top cover of the cap and the lens. The LED is positioned to project light downward towards the lens. The control circuit is powered by the battery to drive the LED when activated. The control button is mounted in the top cover of the cap to activate the control circuit. The lower section is mounted to a base of the lens. The lower section is configured to be removably attached to the beverage container.

Abstract: A chair is presented that includes a pair of chair arms, two pairs of chair legs, and a sheet of fabric. Each chair arm has a concave shape and a concave groove extending along the entire length of a concave surface of the chair arm. Each pair of chair legs is affixed to a bottom surface of each chair arm opposite the groove. The sheet of fabric has a pair of flexible rods. Each rod is affixed to the fabric and is substantially parallel to one another. The sheet of fabric is affixed to the chair by threading each of the rods through a different one of the corresponding grooves.

Abstract: A multiphase voltage controlled oscillator includes at least one ring oscillating unit and a resistor ring; the ring oscillating unit is formed by connecting a plurality of phase-delay elements in cascade and the resistor ring is formed by connecting a plurality of resistor elements in cascade; wherein the connecting nodes of each ring oscillating unit are electrically connected to the connecting nodes of the resistor ring such that the ring oscillating unit can generate a plurality of oscillating signals with uniform phase differences.

Abstract: Receiver signal strength indicator, having an automatic outputting detection circuit, can immediately detect whether its output terminals are connected to a specific apparatus or not. The RSSI comprises an RSSI signal generator, an A/D converter, an automatic outputting detection circuit and at least one output terminal. The automatic outputting detection circuit includes a current detection circuit and an interruption signal generator. When a current passes through the output terminal, the current detection circuit detects the occurrence of the current and generates a push signal. The push signal triggers the interruption signal generator, which in turn generates an interruption signal, and then an RSSI signals are output from the RSSI signal generator due to the interruption signal. The A/D converter converts the RSSI signal into an analog signal. Afterward, the analog signal is output to the exterior through the output terminal.
