Abstract: A rechargeable dual-use transceiver set for audio applications comprises a first transceiver and a second transceiver. The first transceiver includes a device end USB connector; a first connecting end USB connector; and a first transceiver unit. The second transceiver includes a second connecting end USB connector; at least one I/O (input/output) port; a second transceiver unit; and a rechargeable battery. The I/O port may be at least one of an earphone or a speaker. Thereby a reel can be installed to the second transceiver for winding the wire of the I/O port. The transceiver set can be used to a wired device or a wireless device. Furthermore, the second transceiver is rechargeable without using any discrete or separate power supply.

Abstract: A multi-purpose electric heater that can be configured as a baseboard heater or an upright heater is provided. The heater preferably includes a pair of elongate housings that are coupled to a base in a manner that allows them to be moved between horizontal and upright positions. Each housing may include a rotatable portion that can be oriented to direct heat where desired.

Abstract: An improved lavatory cleanser dispensing device that is height-adjustable and capable of quantitatively dispensing cleanser is composed of a fixing member and a shell. The fixing member includes a hanging portion at a top side thereof to be hung on a toilet water tank and a plurality of locating portions formed at a bottom section thereof and in top-down arrangement. The shell includes at least one chamber inside, a plurality of inlets and outlets running therethrough to enable the chamber to communicate with outside, and at lease one positioning portion detachably mounted on the locating portions of the fixing members.

Abstract: A test method and a test device for integrated circuits are proposed. The test device includes: a test platform having a plurality of spaced-apart test tunnels; a test tray defined with board attach areas corresponding in position to the test tunnels, whereby a strip board having a plurality of semiconductor packages can be placed on a board attach area, and aligned with a corresponding test tunnel; and a control mechanism for gradually moving the test tray to perform tests for the semiconductor packages on the strip board. In operation of the test method, first, a plurality of strip boards having semiconductor packages are placed on the test tray, and each corresponds to a test tunnel of the test platform. Then, the test tray is gradually moved in a manner as to perform tests for all semiconductor packages on the strip board step by step.

Abstract: A heater comprising two or more heating units which are rotatably attached to each other about a common axis. Preferably, each heating unit is rotatably attached to the next successive heating unit along a vertical axis by a flanged coupling. Alternatively, each heating unit is rotatably attached to the next successive heating unit along a vertical axis by a pin and slot arrangement. Each of the heating units include a housing having at least one opening and a heater element within the housing.

Abstract: An air purifier unit having a mounting assembly that allows the mounting of the unit underneath a cabinet or on any like flat surface. A cartridge filter is provided and easily ejected or replaced through a filter door in the face of the enclosure. A motor speed indicator circuit enables the user to visually monitor the speed of the motor and blower. Air is drawn into the housing of the unit through an intake opening on the bottom surface of the housing, forced through a cartridge filter, and expelled out an air exhaust opening.

Abstract: An air purifier, an air filter and a method of manufacturing an air filter for an air purifier are provided. The air purifier includes a base assembly, a filter assembly and a grill. A fan is mounted to the base assembly, and draws air through the filter assembly. The base and filter assemblies include adjoining walls having openings which are substantially smaller in area than the areas of the adjoining walls and area through which air is drawn in through the filter assembly. A resilient gasket having a passage approximately the size of these openings is positioned between the adjoining walls. The filter assembly is drawn towards the base assembly when the fan is operated, thereby enhancing the seal formed by the gasket against the adjoining walls. Unfiltered air is accordingly unlikely to bypass the filter assembly. The air filter is manufactured in an efficient manner through the use of a back plate having oblique end portions.

Abstract: A portable heater providing both radiant and forced air heat includes a plurality of vertically oriented, horizontally spaced apart quartz heating tubes is partially surrounded by a common reflector configured to open at an obtuse angle at each quartz tube. The reflector is perforated to allow air to pass out from the interior of the heater. A housing surrounds the reflector and heating elements. A fan located toward the top of the heater draws air inward and down the channels behind the reflector from which it emerges past the heating elements. Control knobs for controlling a thermostat and output power level are located at the top surface of the housing. The heater also has automatic safety controls for shutting off power in the event the heater tips over or overheats, and an overcurrent device.

Abstract: A window fan incorporating a filter. The fan has a low, flat profile for fitting in a window while occupying limited viewing area of the window. The fan includes laterally projecting extensions for sealing a gap which might otherwise exist at the right and left sides of the fan. The fan includes a motorized squirrel cage blower for forcing air through a flow path defined within the window fan. The blower is elongated, and oriented with its rotational axis arranged horizontally to enable the low profile. The filter is washable, and is installed by sliding into a holding chamber, and located serially within the air flow path. The window fan has a manually adjustable air deflector for directing discharged air as desired. The electrical circuit conducting power to the motor includes a touch sensitive switch for on-off control, a thermostatic switch for operating the fan when the touch switch is on and a predetermined temperature is detected, a speed selector switch, and an indicating lamp.
