20150268725 | Systems and Methods for Force-Based Object Manipulation and Haptic Sensations - Systems and methods for force-based object manipulation and haptic sensations are disclosed. One disclosed method includes the steps of receiving a first signal indicating a location of a user interaction and receiving a second signal indicating a first force. The method also includes, if the location of the user interaction corresponds to an object displayed on a display screen: outputting a first haptic signal to a haptic output device to cause a first haptic effect; and outputting a second haptic signal to the haptic output device to cause a second haptic effect if the first force meets or exceeds a first force threshold. | 09-24-2015 |

20120037217 | DISCRIMINATING ELECTROMAGNETIC RADIATION BASED ON ANGLE OF INCIDENCE - The present invention provides systems, articles, and methods for discriminating electromagnetic radiation based upon the angle of incidence of the electromagnetic radiation. In some cases, the materials and systems described herein can be capable of inhibiting reflection of electromagnetic radiation (e.g., the materials and systems can be capable of transmitting and/or absorbing electromagnetic radiation) within a given range of angles of incidence at a first incident surface, while substantially reflecting electromagnetic radiation outside the range of angles of incidence at a second incident surface (which can be the same as or different from the first incident surface). A photonic material comprising a plurality of periodically occurring separate domains can be used, in some cases, to selectively transmit and/or selectively absorb one portion of incoming electromagnetic radiation while reflecting another portion of incoming electromagnetic radiation, based upon the angle of incidence. In some embodiments, one domain of the photonic material can include an isotropic dielectric function, while another domain of the photonic material can include an anisotropic dielectric function. In some instances, one domain of the photonic material can include an isotropic magnetic permeability, while another domain of the photonic material can include an anisotropic magnetic permeability. In some embodiments, non-photonic materials (e.g., materials with relatively large scale features) can be used to selectively absorb incoming electromagnetic radiation based on angle of incidence. | 02-16-2012 |

20130179013 | MAIN PUMP TO AUXILIARY PUMP HAND-OFF STRATEGY FOR MAINTAINING HYDRAULIC PRESSURE IN HYBRID TRANSMISSION - A method and system of providing hydraulic pressure during a transition from gas-powered engine operation to electric motor operation in a hybrid electric vehicle. During the transition, main pressure arising from operation of a gas-powered engine with a main pump is matched with auxiliary pressure arising from operation of a battery-powered electric motor with an auxiliary pump. After matching the main and auxiliary pressures, the auxiliary pressure is boosted to an operational pressure in response to a triggering event. | 07-11-2013 |
20150025750 | TECHNIQUES FOR ROBUST PARK LOCK CONTROL - A technique includes receiving, at a controller of a vehicle, the controller including one or more processors, a first request to calibrate a park lock system of the vehicle. The calibration can include commanding, by the controller, a first actuator to move a second actuator to maximum engagement/disengagement positions indicating maximum engagement/disengagement of a park pawl with/from a park gear of a transmission. The calibration can include determining, at the controller, full engagement/disengagement positions for the second actuator based on the maximum engagement/disengagement positions. The controller can then control the engagement/disengagement of the park lock system using the full engagement/disengagement positions for the second actuator, respectively. | 01-22-2015 |
