An ultra-high-frequency notch filter (100) comprises a capacitor (102) defining a conductive trace (106) on its body (103) and extending between its terminals (104). The trace has an inductance that forms a parallel LC circuit with the capacitance of the capacitor. When mounted on a printed circuit board (120) to connect two segments of a signal line (124), the notch filter and a ground plane (122) of the PCB form a virtual conductive loop having an inductance and a capacitance whose product is the center frequency of the notch of the notch filter. The center ferquency is tuned by varying the width of the trace.

A touch pad device, for use in a portable computer, includes a touch pad housing that is recessed into and integrally formed on a top surface of a key deck. A pad assembly is securely seated into the touch pad housing and includes a touch pad. A pad cover is fastened to the touch pad housing, with the pad assembly installed therebetween, by hooks. Since the touch pad housing is integrally formed on the key deck, the number of component parts of the touch pad device is minimized and the man-hours for assembly is reduced. Further, since the pad cover can be installed and separated from above the key deck, maintenance of the pad assembly is simplified.

A spacer for a nuclear fuel assembly includes dividers orthogonally interdigitated relative to one another defining fuel and water rod cells. The dividers defining fuel rod cells have openings carrying an integrally formed spring which projects into the fuel cell to bear the fuel rod in the cell against an opposite stop carried by an opposing divider. The dividers are arranged in a 10x10 array with diagonally opposing quadrants being mirror images of one another. The dividers are surrounded by a peripheral band with integrally formed stops projecting into the peripheral cells enclosing the spacer.
