Patent number: 5336110Abstract: A connector is described, of the type that has pegs for insertion in holes of a circuit board to securely hold the connector to the board, wherein the pegs can be easily installed, and they assure secure holding despite variations in circuit board thickness and moderate tolerances in the diameters of the circuit board holes. Each of the pegs (41, FIG. 4 ) has a peg body (60) with an axis (62), and a plurality of ribs (71-73) projecting radially outwardly from the periphery of the body. The pegs are constructed of material of lower hardness than the material of the circuit board, so the interference fit between the pegs and circuit board results in flattening of the tips of the ribs and/or shaving of the tips of the ribs. Each peg has a slot (66) extending from the periphery of the peg body to near the axis of the peg body, and a pair of the ribs lie on opposite sides of the slot, so radially-inward pressure on the ribs causes the slot to close slightly and allow the ribs to move radially inwardly.Type: GrantFiled: November 12, 1991Date of Patent: August 9, 1994Assignee: ITT CorporationInventor: Rene A. Mosquera

Patent number: 5325099Abstract: A modular solid-state radar transmitter apparatus for producing waveforms whose amplitude may be varied over time. The transmitter achieves pulse modulation on either an intrapulse or pulse to pulse basis, while at the same time reducing stress on individual solid-state modules. Intrapulse modulation and pulse to pulse modulation can be produced with the disclosed modular solid-state transmitter because the number of modules and the sequence in which they are activated is selectable. These selections provide the various desired levels of transmitted power and thus effectively achieve modulation. In order to achieve this intrapulse modulation, a variable combiner is introduced whose coupling factor is coordinated with the module activations. In one embodiment, variable combining is accomplished by the use of RF switching logic for combining pairs of signals in parallel. In this case, RF switches are programmed to act as a conventional combiner when all modules are active.Type: GrantFiled: April 28, 1993Date of Patent: June 28, 1994Assignee: ITT CorporationInventors: Jeffrey T.
