Abstract: A small, low-profile plug connector for use with electronic devices provides a latching member with a pair of hooks that engage mating holes in a guide frame, and which can be easily delatched from the guide frame or opposing connector or housing. The hooks lock the plug connector into engagement with the frame or housing, but are readily released by way of a simple ramp and lobe mechanism in the plug connector. The ramp and lobe mechanism converts horizontal movement of a pull tab actuator into vertical movement of a latching member such that the hooks are lifted upward and disengaged from the guide frame or housing. The pull tab has a configured shape that fits within the width profile of the connector and which partially envelops the cable.

Abstract: An air flow producer of non-rectangular shape is adapted for installation in a rectangular opening of a drop ceiling. In preferred form, the producer has a circular housing with an open bottom covered with a grill. A fan with a rotary blade assembly is mounted in the housing to produce a downward air flow, and a circular metal band surrounding the rotary blade assembly defines an air discharge zone centered in the grill and an annular air intake zone surrounding the discharge zone. Flow rates are optimized by positioning the band close to the grill. The grill is preferably integrally molded with a rectangular flange that seats in the drop ceiling opening. The flange supports the housing from the framework and closes the opening to prevent the producer from drawing air from the plenum above the drop ceiling.

Abstract: A cable connector is provided that has a connector housing that is thin and takes the form of a wafer. Terminals are held within the housing and termination portions extend lengthwise from the terminals. The termination portions extend out from the housing for terminating bare conductors of signal wires to them. A grounding shield is provided that extends over the signal terminals from their contact portions at the front end of the connector to their rear termination portions. The grounding shield thereby provided a ground extent over the termination area that increases the electrical affinity of the signal wires to the grounding shield so as to reduce crosstalk and noise during operation at high frequencies. In one embodiment, the grounding shield includes a separate extension that is connected to the base grounding shield. In another embodiment, the grounding shield has a length sufficient to extend over the termination area.

Abstract: An air flow producer mounted at the ceiling of a room generates an air flow toward the floor, reducing temperature gradients and improving heating and cooling efficiency. A housing defines a circular cylindrical, vertical flow passage that receives the air flow. A discharge chamber discharges the air flow through a grill toward the floor. The discharge chamber has a cross-section that expands progressively from the outlet of the flow passage to the outlet of the discharge chamber. The air flow through the housing is produced by a fan with a rotary blade assembly, and the blade assembly extends partially into the discharge chamber. The position of the blade assembly and the expanding cross-section of the discharge chamber cooperate to increase air flows through the housing. Optionally, an air intake chamber of generally inverted frustoconical shape may be mounted at the upper inlet end of the cylindrical flow passage to smooth flows further.

Gasket engagement tabs in the top and bottom provide electrical connection between the gasket and panels.

Abstract: A connector for connecting cables to a pin header has a connector body portion that incorporates a strain relief member applied to the cables as part of the connector body portion. The strain relief member includes a cable clamp having a series of grooves that are separated by intervening land portions. The grooves receive the cables and particularly space them. A stop is formed in the clamp to isolate the cable end. The leads of the cable are terminated to corresponding tail portions of contacts of the connector. These tail portions are maintained in the same plane to enhance the electrical performance of the connector. An insulative material is molded over the tail portions and the cable clamp to form a connector with a cable clamp formed integrally with the body of the connector.

Abstract: A tuner is provided for selecting for reception any one of a plurality of channels in a broadband radio frequency signal supplied to its input. The tuner comprises a plurality of stages, at least some of whose gains and power consumptions can be adjusted by a controller in accordance with prevailing reception conditions. A frequency changer and variable gain amplifier provide a first filtering arrangement to reject non-adjacent channels and a tuneable filter rejects substantially all but the selected channel. Signal levels before the first filtering arrangement, between the first filtering arrangement and a second filtering arrangement formed by the tuneable filter, and after the second arrangement are supplied to the controller, which adapts the gain structure and/or individual stage power consumptions according to the prevailing reception conditions so as to provide an adequate performance for demodulation while reducing power consumption when extreme reception conditions are not encountered.
