A head rotator assembly (22) for dynamically compensating for a tape skew of a storage tape that moves over a head (20) in a tape drive (10) comprises a head supporter (230) that is coupled to and supports the head (20), and a supporter mover assembly (232). The supporter mover assembly (232) includes a first actuator (234A) that indirectly rotates a portion of the head supporter (230) about an axis to move the head (20) in an azimuth direction relative to the storage tape to dynamically compensate for the tape skew as the storage tape moves over the head (20). Additionally, the supporter mover assembly (232) can include a first lever (236A) moved by the first actuator (234A) to rotate the portion of the head supporter (230) so that the head (20) moves in the azimuth direction relative to the storage tape to dynamically compensate for the tape skew.
摘要:
A system for estimating an illuminant of a scene that was captured by an input image includes a control system that generates an input gamut that includes the input colors for the input image. Further, the control system compares the input gamut to an illuminant database that includes separate information from a gamut of observable colors for a plurality of possible illuminants to estimate the possible illuminant. Each illuminant can be represented by a separate illuminant gamut. Moreover, each gamut can be organized as a matrix. Additionally, the control system can combine the input gamut with each of the illuminant gamuts to generate a separate union gamut for each of the possible illuminants. The control system can compare the union gamut and the corresponding illuminant gamut for each possible illuminant to estimate the illuminant. After estimating the possible illuminant, the control system performs color correction on the input image.

A laser source assembly for providing an assembly output beam includes a first emitter, a second emitter, and a third emitter. The first emitter emits a first beam along a first beam axis that is substantially parallel to and spaced apart from an assembly axis. The second emitter emits a second beam along a second beam axis that is substantially parallel to and spaced apart from the assembly axis. The third emitter emits a third beam along a third beam axis that is substantially parallel to and spaced apart from the assembly axis. The first beam axis, the second beam axis and the third beam axis are positioned spaced apart about and substantially equidistant from the assembly axis.

A tape drive (232) that receives a tape cartridge (42) having a tape (256) comprises a tape head (280) and a control system (270). The tape head (280) transfers data between the tape drive (232) and the tape (256). The control system (270) utilizes linear parameterization to control the position of the tape head (280) relative to the tape (256). The control system (270) can include a compensator (J) and a filter (Q). The compensator (J) is a combination of the information contained in a nominal control system (370A) and the information contained in a model of the servo system (370B). The model of the servo system (370B) estimates system disturbances that affect the tracking ability of the control system (270). The filter (Q) filters the estimated system disturbances to generate a filtered system disturbance signal. The filtered system disturbance signal is then used to adjust the output of the compensator (J). Additionally, the control system (270) can utilize Youla-Kucera parameterization to control the position of the tape head (280) relative to the tape (256). Further, the control system (270) controls the position of the tape head (280) relative to the tape (256) without the use of a feed-forward sensor.

A ballast includes a power supply subsystem, a power factor correction circuit, a control subsystem and a half bridge. In one embodiment, the power supply subsystem receives an input line voltage that is within a range of approximately 310-530 volts AC or other suitable ranges. Further, in one embodiment, the power supply subsystem provides a rectified DC output. The power factor correction circuit receives the rectified DC output. In one embodiment, the power factor correction circuit includes a boost converter and a buck converter that produce a selected stable bus voltage that is less than approximately 700 volts DC. The control subsystem outputs control signals based on a digital input. The half bridge receives the bus voltage and the output control signals. Additionally, the half bridge outputs a high frequency signal to a lamp. In one embodiment, the control subsystem includes a microcontroller and a ballast controller. Further, in one embodiment, the ballast controller includes a software module that receives the digital input and provides first input control signals to the microcontroller.

A combination for use as a collectible item or a game piece includes a collectible miniature figurine and a first game assembly. The collectible miniature figurine includes a figure body and a figure base that retains and supports the figure body. The first game assembly includes a first game base that is selectively attachable to and detachable from the figure base without deforming either of the bases. Further, the figure base is selectively rotatable relative to the first game base when the figure base is attached to the first game base. Still further, the figure base can be selectively rotatable relative to the first game base in a step-like fashion.

A sensor assembly (51) for sensing one or more fluid properties of a fluid in a subsurface well (12) having a well fluid level (42W), a surface region (32) and a riser pipe (30) includes a sensor apparatus (52) and a pump assembly (54) that are positioned within the well (12). The sensor apparatus (52) includes a sensor (682) that senses one of the fluid properties. The pump assembly (54) can be positioned in an in-line manner relative to the sensor apparatus (52). The pump assembly (54) can be positioned between the sensor apparatus (52) and the surface region (32). Alternatively, the sensor apparatus (52) can be positioned between the pump assembly (54) and the surface region (32). In one embodiment, the sensor apparatus (52) is positioned above the well fluid level (42W). The pump assembly (54) can pump fluid toward the sensor apparatus (52) or the pump assembly (54) can pump fluid to draw more fluid to the sensor apparatus (52). The pump assembly (54) can be a two-line, two-valve pump that is removable from the riser pipe (30). The sensor assembly (51) can include a controller (17) that receives data from the sensor (682) regarding one of the fluid properties of the fluid.

A trading card game (10) includes a first card (212) having only one immovable section (234). The game (10) also includes a second card (314) including a first section (352) and a second section (354). The second section (354) can be slidable relative to the first section (352) so that the second card (314) moves between a first position and a second position. In the first position, a portion of the second section (354) is unexposed to the players. In the second position, the portion of the second section (354) is exposed to the players, and influences the outcome of at least a portion of the game (10).

A pharmaceutical waste disposal assembly (10) includes a receiver body (19), a receiver guide (62), a fluid absorber (70) and a fluid distributor (64). The receiver body (19) receives fluid pharmaceutical waste. The receiver guide (62) guides the fluid pharmaceutical waste into the receiver body (19). The fluid absorber (70) is positioned within the receiver body (19), and is adapted to absorb at least a portion of the fluid pharmaceutical waste that is received by the receiver body (19). The fluid distributor (64) is coupled to the receiver guide (62), and extends at least partially into the fluid absorber (70) so that the fluid distributor (64) distributes the fluid pharmaceutical waste within the fluid absorber (70). The fluid distributor (64) includes a plurality of distributor apertures (278) that allow the fluid pharmaceutical waste to flow from the receiver guide (62) to the fluid absorber (70).
