A power and control architecture employing circuitry that sequentially regulate power flows from independent solar-array sources or a mixture of power sources providing power to a common load. The device may be used on a satellite with solar-array sources; however it may also be used on ground based systems. Stiff bus voltage regulation is obtained by tightly controlling the most recently activated power-processing channel while keeping the previously activated power-processing channels in the Maximum Power Tracking mode to supply maximum power to a common load. The remaining power-processing channels are turned off or operated in stand-by mode. In an alternative system, with primary design goal of uniform power sharing among solar-array sources, all solar array sources are activated with uniform power sharing at light load and, as load demand increases, sequentially controlled to operate in the Maximum Power Tracking mode one solar array source at a time as necessary.

The invention provides an animated display in which an illumination source projects light through a platen and a transparency that contains alternative translucent images. The invention involves using an electronic processor to drive two highly controllable motors. Light sensors are used to determine the alignment of a mask over said transparency relative to the light source. The sensors provide input to the processor to allow the two motors to align the mask horizontally. The motors are used to drive the mask vertically in order to change the projected image. In a second embodiment, the lens is a lenticular lens behind the translucent raster multiple image film. A motor acts to drive the mask to align the opaque or image portions of the raster to the focusing portion of the lenticular lens. A lenticular lens may focus on the image line for one of the images on the film.

A matrix-connected driver for multiple two-phase motors includes circuit rows and columns of input and output connections for the phases of networked two-phase motors. Phases of multiple motors share the same input line and phases of multiple motors share the same output line but no motor phase shares both the same input and the same output. Buffers that may be transistors power each input and output line. The input and output lines may be alternatively positively powered high or grounded low using the buffers. In this fashion individual phases may be singly powered using selected pairs of the buffers without causing the other phases to be powered whether high or low. A processor such as a microprocessor drives the buffers. The usage of common input and output lines or otherwise referred to as columns and rows allows the same number of motors to be single phase mode driven with much less wires. The device is particularly effective for driving multiple motors whereby the electronics are not in the same environment as the motors. This may be motivated due to extreme temperatures, radiation, or remoteness of the environment, so that the chance of a requirement to access the hostile environment will be minimized.

A rotational sensor for use with an in-vehicle navigation system , a navigation system that uses the sensor, and a vehicle with the sensor installed. The rotational sensor is created by placing two gravitational accelerometers configured at 90 degrees with respect to one another and mounted at the center of a vehicle wheel. As this resulting sensor is rotated, sine and cosine signals with a quadrature relationship are generated with respect to the earth's gravity vector, from which both rotation and direction of rotation can be determined. These signals may then allow the counting of the turns of the wheel, thus estimating the distance and the rate at which the vehicle has moved. A self-contained version of this device including a transmitter can relay this information to a receiving unit located within the vehicle. When one of these devices is located on each of the steerable wheels of the vehicle, the relative heading-direction of the vehicle may also be estimated.

A remote controlled actuator system has a motor with a drive or screw shaft. The motor drives a sliding element propelled by the screw shaft. The control circuit may include steering diodes to minimize wires where there is sensing or more than one actuator. A remote controller may direct motor movement of individual actuators without a local controller. The remote actuator may be used to sense remote position through the steering diodes. There is a bipolar and bi-level drive circuit providing the step voltage to achieve high performance motor movement. The guideway may have an internal keyway along with an anti-rotation sliding bearing protected against rotation by the keyway. This anti-rotation sliding bearing restricts the piston to linear travel along the driving motor lead screw thread. The position sensor may include a resistive element sliding contact mounted to the sliding piston. A special coaxial mechanical coupling method simplifies installation.

A bowling ball drilling apparatus for drilling variable size holes includes a table having an upwardly opening ball supporting pocket. A boring apparatus is mounted below the table for reciprocation in a generally vertical direction in a path intersecting the pocket. A carriage moves the boring apparatus in the path. The boring apparatus has an output shaft rotatable about a vertical axis. An adjustable boring head is connected to the output shaft for rotation therewith, the boring head receiving a boring tool and being variable adjusted to offset the boring tool horizontally relative to the vertical axis so that the boring tool orbits about the vertical axis to produce a variable size hole in the bowling ball dependent on an amount of the offset.

The length of a drilling cycle in a bowling ball fitting and drilling method is reduced in an apparatus including a fitting apparatus (10) usable by a bowler to determine the size of a thumb hole and at least one finger hole to be drilled in a bowling ball and including a drilling apparatus (14) having a ball support (22), a rotatable drilling tool (30) movable relative thereto and a drive (36) for the drilling tool (30). A dove tail slide connection (50), (52) provides for moving the drilling tool (30) in an orbital path and an adjustment mechanism (56), (58), (60), (62), (70), (84) is provided whereby the diameter of the orbital path may be varied to vary the diameter of a hole drilled in the ball. A control motor (122) is responsive to the fitting apparatus (10) to operate the adjusting mechanism (56), (58), (60), (62), (70), (84). The control motor 122 is carried by the drive (36) and thus, may be adjusted 'on the fly'.

Delays in fitting and drilling bowling balls are eliminated in a point of sale bowling ball fitting and drilling apparatus. A fitting apparatus (30) includes two movable finger blocks (34), (36) and a thumb aperture (38). Through the use of inserts taken from a group of inserts (150), the fitting apparatus (30) may be utilized to generate control signals to a drilling apparatus (46). A ball (204) may be positioned within the drilling apparatus (46) and insert receiving holes drilled therein in response to the information received by the drilling apparatus (46) from the fitting apparatus (30).
