20090246920 | METHODS FOR NORMALIZING STRAIN IN A SEMICONDUCTOR DEVICE - The electrical performance enhancing effects of inducing strain in semiconductor devices is made substantially uniform across a substrate having a varying population density of device components by selectively spacing apart the strain-inducing structures from the effected regions of the semiconductor devices depending upon the population density of device components. Differing separation distances are obtained by selectively forming sidewall spacers on device components, such as MOS transistor gate electrodes, in which the sidewall spacers have a relatively small width in regions having a relatively high density of device components, and a relatively larger width in regions having a relatively low density of device components. By varying the separation distance of strain-inducing structures from the effected components, uniform electrical performance is obtained in the various components of the devices in an integrated circuit regardless of the component population density. | 10-01-2009 |

Biometrics features that uniquely identify an individual are selected. If a real-time biometrics scan of the individual does not match a stored image of an authorized operator, the interlock system will lock the mechanical device to prevent operation. The interlock system may be used in conjunction with a breath alcohol analyzer to determine impairment. If the biometrics testing indicates that the individual is required to be tested for impairment, the mechanical device will not operate until the testing is completed. If the biometrics testing automatically indicates that the operator of the mechanical apparatus and the individual exhaling into the breath alcohol analyzer component of the ignition interlock is not the same person, the ignition system of the mechanical apparatus, which operates in conjunction with the ignition interlock of the present invention, provides a programmable software option to prevent the apparatus from starting. If the test indicates that the individual is impaired the interlock system will lock the mechanical device to prevent operation. | 05-06-2010 |

20110183794 | PEDAL DRIVEN APPARATUS HAVING A MOTOR - A hybrid bicycle is provided which is manually propelled, but may include a motor unit for assisting forward propulsion of the bicycle. The bicycle has a control system for providing a control input for another component of the bicycle. Where that component comprises the motor, the control input is for increasing drive power applied by the motor unit to said bicycle. Where the component is a continuously variable transmission (CVT) for the bicycle, the control input is for continuously varying the gearing ratio of the CVT. Located adjacent a drive sprocket is a moveable plate member. The plate member and the drive sprocket are mounted for rotation about an axis of rotation of a pedal spindle, although the sprocket is not fixed for rotation with the pedal spindle. The drive sprocket is loosely coupled to the plate member with the plate member being moveable relative to the sprocket by a limited distance in a rotational direction. The plate member acts on a lever mechanism when it is moved relative to said drive sprocket such that any movement of the plate member results in an axial movement of an actuator member which triggers the control system to generate the control input in response to the amount of any movement of the plate member relative to the sprocket. | 07-28-2011 |
20110183805 | MOTOR HAVING AN INTEGRATED TORQUE SENSOR - A motor unit comprises a housing for containing a motor, a motor shaft for receiving a motor provided driving force, a torque sensor mechanism for detecting torque, and a controller for controlling power to the motor in response to a detected amount of torque. An actuator couples the torque sensor to a sensor of the controller. The actuator is configured to move relative to the controller sensor thereby causing the sensor to produce a signal indicative of the detected level of torque. The controller is contained within the housing of the motor. The motor unit may also have an auxiliary shaft for receiving an externally provided driving force with a first torque transmission path for transferring the externally provided driving force to a drive mechanism and a second torque transmission path for transferring the motor provided driving force to said drive mechanism. A first one way drive means is provided in the first torque transmission path between the auxiliary shaft and the drive mechanism such that when the drive mechanism is being driven by the motor provided driving force through the second torque transmission path, the auxiliary shaft is able to freewheel. The motor unit can drive any apparatus, but may be used in a pedal driven apparatus such as a bicycle where an externally provided driving force is provided by manually operable pedals of said apparatus which are fixed for rotation with the auxiliary shaft. In this case, the auxiliary shaft comprises a pedal spindle of the bicycle and the drive mechanism comprises a sprocket or belt drive. | 07-28-2011 |
