Novel loop polymers having a polymeric backbone and a plurality of olefinic groups which have been converted to closed loops by reaction with difunctional organic compounds reactive with said olefinic groups, said olefinic groups from which the loops are formed may either be present within the backbone and/or pendent from the polymeric backbone. The loop polymers may also have hydroxy or carboxy groups which can be capped with diisocyanates or epoxies, respectively.

An exercising loop including a steel open loop having two opposite ends facing each other and spaced by a gap, a coil spring mounted on the steel open loop, a collapsible cloth sleeve sleeved onto the coil spring around the steel open loop, a connecting tube covered with a sponge covering and fixedly connected between the two opposite ends of the steel open loop, and two grips respectively mounted around the two opposite ends of the steel open loop and fixedly connected to the two opposite ends ...

An integrated circuit phase-locked loop includes a phase/frequency detector, a charge pump, and a voltage-controlled oscillator (VCO) which are coupled together in series. The VCO has first and second VCO control inputs, and has a VCO output which is coupled to the phase/frequency detector. An off-chip loop filter input is coupled between the charge pump and the first VCO control input for coupling to an off-chip loop filter. An on-chip loop filter is coupled between the first VCO control input ...

A loop pin with high tensile rupture strength has an insertion head portion with an appropriate mating part on one end and a socket portion comprising a hole for irreversibly passing the insertion head portion provided on the other end, wherein one part of the insertion head portion has formed on it two parallel surfaces along the axial direction thereof.

A bowstring release device includes a housing having a longitudinal axis and a center slot opening at a forward end thereof; a sear component pivotably mounted in the housing, the sear component having a jaw movable between a first position where the center slot is open and a second position where the center slot is closed; a trigger component pivotably mounted in the housing, the trigger having a forward projection engageable with the sear component to hold the sear component in the first posit...

A loop scheduler in a software compiler system for generating a schedule for executing in a target computer loops of instructions contained in a computer program is described. The loop scheduler operates by searching for an optimal loop schedule for executing a particular instruction loop in the target computer. The loop scheduler then identifies loop overhead instructions and non-loop overhead instructions in the particular instruction loop. A replicated loop schedule is generated by the loop s...

A loop filter (4) having an adapt input (26), a normal input (24) and an output (23) is disclosed. Each of the inputs (24, 26) is connectable to mutually exclusively operable current sources to operate the loop filter (4) in an adapt and a normal mode respectively for controlling a voltage controlled oscillator (14) connectable to the output. The loop filter (4) includes a circuit (27) which when operated in the normal mode is connected between the normal input (24) and the output (23) to introd...

A loop filtering method and a loop filter therefor are provided. The loop filtering method includes the steps of: (a) generating a binary edge map by comparing a value obtained by operating each pixel of the image data using a predetermined one-dimensional gradient operator with a predetermined threshold value; (b) applying a filter window with a predetermined size to the generated binary edge map to check whether an edge information exists within the filter window; (c) filtering the pixel value...

A device and method for synchronizing a local clock to a reference clock. The device uses a frequency acquisition loop and a phase acquisition loop. The frequency acquisition loop delays the reference clock to produce an intermediate clock which falls within the operating range of the phase acquisition loop. The phase acquisition loop then delays the intermediate clock to produce a local clock synchronized to the reference clock.

In a phase locked loop, a loop filter is provided between a charge pump and a VCO. The loop filter includes a passive integrator connected to a non-inverting input of an operational amplifier which supplies a tuning voltage to the VCO. The passive integrator functions to short-circuit pulses from the charge pump to ground, to prevent them from appearing at the output of the operational amplifier. The VCO tuning voltage area may be expanded by shifting a DC voltage level at the inverting input of...
