摘要:
A collapsible table includes a blow-molded table top and two opposing collapsible support stands mounted on a bottom of the table top. The support stands are supported by articulated support braces attached to cross braces that span the underside of the table top. At opposing ends of the cross braces are substantially U-shaped brackets that receive leg members of the support stands when the support stands are in a collapsed position.
摘要:
A collapsible table has an elongate blow-molded table top comprising two table top halves. A support frame comprising first and second pairs of support members is attached to the bottom surface of the table top halves. A pair of hinge assemblies pivotally connect the first pair of support members to the second pair of support members so that the two table top halves are pivotally connected together. This allows the first and second table top halves to be folded together in a storage position. At least one of the hinge assemblies includes a spring-loaded latch member for latching and unlatching the hinge assembly. When the hinge assembly is latched, the table top halves are locked into an open position for normal use. When the hinge assembly is unlatched, the table top halves may be folded together for storage.

摘要:
A collapsible table has a blow-molded tabletop comprising two table top halves. Each tabletop half has a substantially planar top surface, a bottom surface opposite the top surface, an inner edge, and an opposing outer edge which is substantially parallel to the inner edge. A hinge assembly pivotally connects the two tabletop halves along their inner edges, allowing the two tabletop halves to be folded together into a storage position. Four collapsible legs are attached to the bottom surface of the tabletop halves. Each collapsible leg is operable to collapse independently of any of the other legs. A first pair of the legs collapse to positions which are substantially parallel to the outer edges of the tabletop halves, and a second pair of the legs collapse to positions which are substantially diagonal to the outer edges of the tabletop halves.

A latching system for a foldable table having two tabletop halves each having a bottom surface and an end surface includes a receiver disposed on the end surface of the first tabletop half and a latching mechanism disposed on the end surface of the second tabletop half. The latching mechanism has an L-shaped anchor and a pivoting clasp. A bottom leaf of the anchor is fastened to the bottom of the second tabletop half and an end leaf of the anchor is fastened to the end surface of the second tabletop half with a plurality of fasteners. The anchor and clasp have one or more hinge barrels for receiving the hinge pin so that the hinged clasp pivots about the hinge pin relative to the anchor. The hinged clasp detachably mates with the receiver and thereby latches the two tabletop halves in a storage position.

A transistor circuit with estimating parameter error and temperature sensing apparatus using the same are provided. The temperature sensing apparatus measures and calculates a parameter error of transistor which is driven by different currents in advance. And the temperature sensing apparatus compensates an error occurred during temperature measurement using the acquired the parameter error so as to obtain an accurate environment temperature.

A differential reference voltage generator generates a first differential reference voltage and a second differential reference voltage. The differential reference voltage generator includes a first operational amplifier, a first transistor, a first resistor, and a second resistor. The first operational amplifier has a negative terminal adapted to receive a reference voltage. The first transistor has a source receiving a power supply voltage and has a gate electrically connected to an output terminal of the first operational amplifier. The first resistor has a first terminal electrically connected to a drain of the first transistor, and has a second terminal electrically connected to a positive terminal of the first operation amplifier. The second resistor has a first terminal electrically connected to the second terminal of the first resistor, and a second terminal electrically connect to a current mirror.

An interference-resistant wireless audio system includes a transceiver for transforming an audio signal into an RF signal, and a receiver for receiving RF signals in the air. The transceiver has an audio signal receiver, an audio data format converter, a frame and coding unit, a modulation module, an RF transceiver, a receiving/transmitting switch controller, an RF signal detector, and a channel switch controller electrically connected to the RF signal detector for controlling the RF transceiver to switch the used channel to another one after receiving a switch signal generated by the RF signal detector
摘要:
An electrode structure adapted for high applied voltage is provided, which comprises a conductive plate substrate and a covering layer disposed thereon such that a covering percentage of the covering layer over the conductive plate substrate is more than 50%. Since area of the conductive plate substrate covered by the covering layer is larger than the area exposed, the possibility of arcing is reduced and the breakdown voltage applied to the electrode structure may be increased.
