Abstract: Individual weights and a related kit for adjustably weighting a golf club head are provided, allowing a golfer to fine-tune the club for his or her swing. The kit is useable with a club head that defines a plurality of weight recesses spaced about the club head. The kit includes a plurality of weights, including weights of different mass. Each weight is sized to be threadably received within a recess of the club head. Varying placement of the weights enables a golfer to vary impact conditions in the club head, for optimum distance and accuracy. The kit may further include a tool having an engagement end configured to operatively mate with the fasteners of the weights. The tool preferably includes a torque limiting mechanism configured to inhibit over-tightening of the weights into the recess of the club head. The tool and weights may be provided along with the golf club.

Abstract: A method of manufacturing a face plate for a golf club head is presented to provide face having substantial thickness variation for enhanced performance. The method includes the steps of providing a rolled sheet of metal material having an initial thickness and forming a blank having a prescribed outer shape from the material. The method also includes machining a second side of the blank such that the resulting face plate has a variable thickness. The machining is such that the plate has a first thickness less than or equal to the initial thickness, a second thickness less than the first thickness and a third thickness less than the second thickness. The machining is performed over a substantial portion of the surface area of the second side. Either a CNC lathe or milling machine may be used; however, for an axisymmetric face thickness a CNC lathe is preferred and for an asymmetric face thickness a CNC end mill is preferred. The club head may be a wood-type or iron, and titanium or steel alloys may be used.

The mass element also has an aperture configured to receive the fastener flush. The fastener removably attaches the weighting assembly to the selected wall of the club head. Pressure from the fastener attachment provides a press-fit of the mass element in the tapered recess of the selected wall.

Abstract: A scannable flip flop for space-based LSSD testable integrated circuits. A scannable register can be formed from the scannable flip flops. The scannable flip flops can be radiation hardened. Each scannable flip flop can include a 2:1 input multiplexer, a first latch and a second latch. The input multiplexer is coupled to the first latch by a pair of pass gates. The pass gates are gated by a first clock input signal. A second pass gate pair couples the first latch to the second latch. A second clock input signal gates the second pass gate pair. The first and second clock input signals are non-overlapping. The latch can be employed in edge triggered logic ECAD tools for designing IC. The resulting IC logic can be tested using LSSD test testing techniques and patterns.

Abstract: An improved electrochemical generator is disclosed. The electrochemical generator includes a thin-film electrochemical cell which is maintained in a state of compression through use of an internal or an external pressure apparatus. A thermal conductor, which is connected to at least one of the positive or negative contacts of the cell, conducts current into and out of the cell and also conducts thermal energy between the cell and thermally conductive, electrically resistive material disposed on a vessel wall adjacent the conductor. The thermally conductive, electrically resistive material may include an anodized coating or a thin sheet of a plastic, mineral-based material or conductive polymer material. The thermal conductor is fabricated to include a resilient portion which expands and contracts to maintain mechanical contact between the cell and the thermally conductive material in the presence of relative movement between the cell and the wall structure.

Abstract: An in-situ thermal management system for an energy storage device. The energy storage device includes a plurality of energy storage cells each being coupled in parallel to common positive and negative connections. Each of the energy storage cells, in accordance with the cell's technology, dimensions, and thermal/electrical properties, is configured to have a ratio of energy content-to-contact surface area such that thermal energy produced by a short-circuit in a particular cell is conducted to a cell adjacent the particular cell so as to prevent the temperature of the particular cell from exceeding a breakdown temperature. In one embodiment, a fuse is coupled in series with each of a number of energy storage cells. The fuses are activated by a current spike capacitively produced by a cell upon occurrence of a short-circuit in the cell, thereby electrically isolating the short-circuited cell from the common positive and negative connections.

Registration members maintain rotationally and axially alignment of the first and second openings of the first and second collars at a conduit interface. A retaining mechanism maintains axial engagement of the first collar with the second collar. In one embodiment, the registration system is also a fastening system.

Abstract: A clock splitter circuit for providing a Single Event Upset (SEU) tolerant clock signals to latches in a space-based environment. The splitter circuit includes an event offset delay. The event offset delay receives an undelayed clock signal and generates an undelayed inverted clock, a delayed clock signal and an inverted delayed clock signal. The delayed clock signal and the inverted delayed clock signal are delayed by the known duration of Single Event Effects (SEE) on logic. The delayed and undelayed clock signals are passed to a pair of event blocking filters which block any disturbance in the undelayed and/or undelayed clock signals. The event blocking filters each generate a pair of in-phase inverted output signals. The event blocking filters are designed such that both pairs of outputs may not be low simultaneously.

Abstract: A light directing, load bearing, thermally protective coupling for connecting a light conduit, such as a light pipe, to a light source includes a body member having a first end connected with the light source and a second end connected with the light pipe. The body member contains a longitudinal channel which extends from the first end to the second end and includes an inner surface defining the channel which directs light from the light source, through the coupling, to the light pipe. To reduce light loss, the inner surface is provided with a highly reflective finish. The coupling is formed of a thermally conductive metal which dissipates heat from the light source and has a length sufficient to produce a temperature drop which allows the light pipe to be connected with the coupling without damaging the light pipe.

Abstract: A mounting assembly for mounting a light pipe lighting system on a support surface includes an elongate support rail connect to the light source and a hanger bracket connect to the elongate support rail. The support rail includes oppositely extending longitudinal flange portions which slidably engage the hanger bracket and thereby serve to connect the support rail with the hanger bracket. The hanger bracket can be either slidably supported on the support rail to allow the light source to move relative to the support surface or the hanger bracket can be fixed at various locations along the support rail. The elongate light source support rail is connect to the light source with a bracket or with a casing which encloses the light source, and the light source support rail can be further connected with an associated light pipe support rail to transmit axial forces between the light pipe and light source.
