An improved golf club with controllable dynamic characteristics is provided with a weighting chamber of controllable weight rigidly secured within an elongated cavity defined through the head of the golf club. The chamber is dynamically weighted by providing a volume of liquid-like material such as mercury within it and has an elongated cavity defined through the cross-section of the club head. The cavity consists of a pair of interconnected cylindrical sections and is provided with a threaded s...

A sanitary napkin is provided with a positioning strap in slideable contact with a low friction baffle which is attached to the bottom of the napkin. The contact between the positioning strap and the baffle is maintained by a retention strap attached to the napkin which encircles the positioning strap. Attachment means are provided at each end of the positioning strap on the surface opposite that in slidable contact with the baffle.

A selective true or complement storage latch is disclosed which includes a data input switch having an input node connecting to a binary bit input source, a control input for accepting a first or second control state, a first data output node which is selectively connected to the data input node when the control input is in the first state and a second data output node which is selectively connected to the data input node when the control input is in the second state. There is also a first inver...

A dynamically illuminated guitar (10) for producing visual and sequential lighting effects on the guitar body (20) caused by spontaneous or deliberate hand and body movements of the guitarist and by external light sources. A plurality of light-emitting diodes (30) through (93) embedded into the guitar face and arranged in aesthetically pleasing designs serve as the display medium. A variety of different light display modes is selected by changing the orientation of the guitar (20) to cause a gro...

A computing system is presented which has a central processing unit (CPU) and peripheral devices. Identification registers associated with each peripheral device may be accessed by the CPU to identify characteristics of individual peripheral devices. Additionally, configuration registers within each peripheral device allow a particular peripheral device to determine whether instructions from the CPU are addressing that particular peripheral device.

A data processing system in which interleaving among memory controllers may be controlled. The interleaving is carried out on a double-word basis, and the state of the double-word address bit is used to select the bus address of the memory controller in which double-words having that address bit are stored. The dynamically controllable interleaving allows greater flexibility in the design of the memory controllers in a data processing system.

A thermoplastic elastomer is described which comprises a blend of (a) a carboxylated butadieneacrylonitrile elastomer and (b) an ethylene/acrylic acid copolymer which has been at least partially neutralized with a metal ion, the blend of (a) and (b) having been dynamically crosslinked with an epoxy crosslinking agent having a minimum of 2 epoxy moieties per molecule.

A dynamically balanced ion generator is provided which incorporates a detection screen and feedback loop to ensure that the number of positive and negative ions emitted from the generator are substantially equal. The detection screen is located between the ion generating electrodes and the exit port of the device, and is contructed of conductive material which captures a predetermined percentage of ions emitted by the electrodes. The detected imbalance is corrected through a feedback loop compri...

A dynamically reconfigurable array logic (DRAL) is capable of in-system logical reconfiguration in real time and comprises a RAM programmable logic array of bits, each bit comprising a fuse connection between logic elements. I/O means are coupled to the RAM programmable logic array for logical selection of registered output. A first register is coupled for receiving data and high-level commands. A sequencer includes a pair of up/down counters and functions to generate addresses. A timing device ...

An oscilloscope provides adjustable control of the reference voltage level to the trigger comparator to calibrate the trigger for both gain and offset. An internal computer in the oscilloscope provides a digital input value to a gain digital-to-analog converter (DAC) the analog output of which is provided to the reference input of a level DAC. The level DAC also receives digital input from the control computer and provides its analog output to the reference input of the trigger channel comparato...
