Haptic sensations for tactile feedback computer interface devices. In one method, a tactile sensation is output during the interaction of a cursor and a graphical object, the tactile sensation being based on a periodic waveform and having a frequency correlated with a size of the graphical object interacted with the cursor. Another method includes receiving an indication of a position of a cursor, causing the cursor to snap to a graphical object, such as a line, when the cursor is within a predetermined distance so that the cursor can be moved along or within the graphical object, and enabling the output of a vibration sensation while the cursor is moved along or within the object. In another method, a tactile sensation includes a pop sensation that is a short, high magnitude sensation, and then a ringing sensation during or immediately after the output of the pop sensation and which can fade in magnitude over time.

A correlator system for automatic car wash has roller assemblies for supporting the front left and right wheels of a vehicle entering a car wash line. A set of guide rails or bars cooperate with the roller assemblies to adjust axial displacement and angular misalignment between the vehicle's front end and a conveyor track transporting the vehicle through the car wash facility. The rollers in the roller assembly rotate freely with minimal friction, axially displacing the front end of the vehicle and adjusting the angular misalignment of the front wheels. The low friction, easy-to-rotate rollers are provided with a plurality of braking elements that generate friction against the rollers, retarding their rotation when a worker steps thereon. The friction generated by the braking elements is insufficient to prevent roller rotation during alignment of the front end with the conveyor track. Injuries to car wash personnel caused by loss of balance when stepping on the rollers are virtually eliminated, and an accurate alignment of the vehicle's front end with the car wash conveyor track is reliably achieved.

The invention is directed to an implanted microphone having reduced sensitivity to vibration. In this regard, the microphone differentiates between the desirable and undesirable vibration by utilizing at least one motion sensor to produce a motion signal when an implanted microphone is in motion. This motion signal is used to yield a microphone output signal that is less vibration sensitive. In a first arrangement, the motion signal may be processed with an output of the implantable microphone transducer to provide an audio signal that is less vibration-sensitive than the microphone output alone. Specifically, the motion signal may be scaled to match the motion component of the microphone output such that upon removal of the motion signal from the microphone output, the remaining signal is an acoustic signal.

A damper pin is disposed between adjacent buckets of a turbine rotor. A first bucket has circumferentially extending supports defining a pair of axially spaced surfaces on which a damper pin rests in a cold condition of the turbine. The adjacent bucket is undercut adjacent its platform to provide an angled surface overlying a generally correspondingly angled surface of the damper pin. The damper pin fits slightly loose within the recess and, upon turbine rotation at speed, the angled surfaces of the damper pin and recess cooperate to bias the damper pin against the first bucket whereby the damper pin engages both buckets and dissipates vibratory action.

A cushion for supporting a user relative to a support surface is provided. The cushion has material with sufficient flexibility to deform under a weight of the user and sufficient resilience to return to its original state when the weight is removed. A supporting face contacts the support surface and is characterized by a plurality of points. The supporting face is contoured such that, when the cushion is in an unloaded configuration, a first subset of the plurality of points contact the support surface and a second subset of the plurality of points do not contact the support surface. When a user then sits on the cushion so that it is in a loaded configuration, at least some of the points in the second subset are displaced under the user's weight and contact the support surface. The cushion thus both bends and compresses to distribute the weight of the user.

A field-effect transistor (FET) device and method of fabrication uses an electrically interconnected polycrystalline or microcrystalline silicon carbide (SiC) gate having a lower electron affinity and higher work function than a polysilicon gate FET. The smaller threshold voltage magnitude of the SiC gate FET allows reduced power supply voltages (lowering power consumption and facilitating downward scaling of transistor dimensions), and enables higher switching speeds and improved performance. The smaller threshold voltage magnitudes are obtained without ion-implantation, which is particularly useful for SOI and thin film transistor devices. Threshold voltage magnitudes are stable in spite of subsequent thermal processing steps. N-channel threshold voltages are optimized for enhancement mode.

A fault handling system for short circuit recovery in three-phase multiple-level inverter bridges, used to drive inductive loads, to assure a proper sequence for turning-off switches in the inverter bridge. Switches are selected for use in the inverter bridge so that outer switches toward the most positive and most negative bus voltage levels of the inverter bridge have lower transconductances than inner switches closest to an output phase of the inverter bridge. Additionally, driver cards driving outer switches utilize lower magnitude excitation control signals than driver cards driving inner switches. Driver cards driving outer switches, when detecting desaturation of an on-state switch, are set to automatically command the outer switch to an off-state, whereas driver cards driving inner switches wait for instructions from a controller before taking action.

A patient who qualifies according to the invention can be termed a reverse remodelling responder (RRR) or the like.

The number of edges where the difference between the luminance gradation values of adjacent pixels is equal to a predetermined edge comparison value or larger is counted, and the counting result is set as a second count value. The afterimage strength level region is calculated based on the first and second count values.

A treat dispensing pet toy comprises a hub assembly having first and second hubs and an axle interconnecting the hubs. A barrel is mounted over the axle and is disposed between the hubs. The barrel has an interior chamber to hold treats. A treat dispensing opening is formed on the barrel and communicates with the interior chamber. When the pet toy is contacted with sufficient force, the hub assembly and barrel independently rotate thereby establishing a rotational differential. Treats fall through or are otherwise ejected from the opening in the barrel. According to a method of dispensing treats, the barrel and hub assembly independently rotate at different rotational speeds to affect the rate of dispensing treats.
