The electronic roll-along switch consists of several input multiplexers, each having a number of inputs that are connected to seismic detectors, and an output line. A plurality of multiple-input sample-and-hold modules are provided. Corresponding inputs of the respective sample-and-hold modules are paralleled. The output lines of the input multiplexers are connected in consecutive order to the paralleled input of the sample-and-hold modules. The output of each sample-and-hold module is connected...

A seismic prospecting roll along switch incorporating electronically controlled switches in an improved switch arrangement requiring far fewer switches than previous systems. In a simple form, one switch is provided for each geophone input with one contact of each switch connected to one of the inputs and the other contact of each switch connected in pairs, appropriately selected, to the inputs of amplifier and filter channels. A controller is provided for electronically closing the appropriate ...

In a vehicle having a chassis and at least one wheel assembly, where the wheel assembly includes a wheel support member, a damping mass, a damping spring for connecting the damping mass to the wheel support member, and a mechanical resistive member in parallel with the damping spring, a suspension connecting the wheel assembly to the chassis, the suspension supporting the weight of the vehicle and isolating the wheel motion from the chassis motion, and at least one actuator for providing force b...

A device for moving a tool along a passage, particularly for use in medical procedures, has two different aspects. In one aspect, a tool, e.g. a colonoscope, is surrounded by a sheath. The sheath has an inflatable region for engaging the passage wall, e.g. a colon. An annular extension region of the sheath is provided which becomes part of the inflated inflatable region thereby increasing its length as the fluid pressure acts against a head of a tool to draw the tool along the passage. The annul...

The present invention includes a doll that has a torso hingedly attached to a pair of legs. Springs are attached to the torso and legs for exerting a spring force that keeps the torso and legs in a substantially planar position. A motor mechanism attached to the torso and legs for moving the torso and legs towards each other against the springs. A circuit board in communication with the motor mechanism controls the torso and legs such that the doll hops along a surface.

A split hinged sleeve circumscribingly engages a substantial length of stranded aluminum cable and includes a plurality of diametrically opposed wedges extending laterally from the sleeve. The sleeve is mounted within a frame having bearing surfaces contacting each of the wedges. On exerting a pulling force upon the frame, which force is resisted by the cable, the bearing surfaces act upon the respective wedges to force the sleeve to grip the cable and place the cable in tension.

A garment bag that can be carried alone or attached to a carrying case having two sides for housing a garment piece therebetween, a zipper opening through which said garment piece can be inserted. Male and female snap pairs are located along the two sides of the garment bag for maintaining said garment bag in a two folded state such that said garment piece will remain unwrinkled therein. Two carrying case hook-ups having two elongated straps, one ending in a female clip and the other ending in a...

A system and method for stitching characters along a curve is disclosed. The alphabetic characters, numerals, symbols, designs, etc. to be sewn or embroidered, along with various other parameters, such as the initial radius and angular displacement of the curve on which the selected characters, etc. are to be stitched, are entered into the system by the operator. The system transforms the stitch points within each selected character, etc. into a new set of stitch points such that the selected ch...

A conduct-along system that can give expressions to sounds and/or images, in which expressions are added to sounds and/or images following the playback of sounds and/or images in real-time based on any one or any combination of parameters, such as tempo, intensity, beat timing and accent, detected from the movement of an input device. The conduct-along system detects any one or any combination of parameters, such as tempo, intensity, beat timing and accent, from the movements of the input device...

An accessory kit for use with a piano of the grand or baby-grand type. The accessory kit includes a dolly which can support a piano in addition to supporting a footrest railing in a surrounding relationship to the legs of the piano, and a removable counter top or bar that can be mounted to the sound box of the piano. With the accessory kit patrons can sit around the piano and sing along while consuming their drinks and food in comfort.
