20140277765 | HUMAN-BUILDING INTERACTION FRAMEWORK FOR PERSONALIZED COMFORT DRIVEN SYSTEM OPERATIONS IN BUILDINGS - A computer data processing system may provide control information for controlling how an environmental control system controls an environment within a building. The computer data processing system may receive and store reports from multiple users and/or may receive and store reports at different times from a user. Each report may provide information concerning how the user perceives the comfort level of the user's environment at the time the user supplies the information. The computer data processing system may determine and generate the control information for controlling how the environmental control system controls the environment based on the information concerning how each user perceives the comfort level of the user's environment at the time each user provides the information. In addition or instead, the computer data processing system may determine and generate such control information based on the information concerning how a user perceives the comfort level of the user's environment at the different times the user supplies the information. | 09-18-2014 |

20090318077 | Television Audio via Phone - Television audio via phone is described. In embodiment(s), a request for a television program or television channel can be received from a mobile phone, such as via a mobile communications network. A video feed of the television program or channel can be accessed to obtain television audio that corresponds to the television program or channel, and the television audio can then be communicated to the mobile phone to render as a telephone communication. | 12-24-2009 |
20090318173 | Telephone Control Service - A telephone control service is described. In embodiment(s), a request to interface with a content distributor can be received from a mobile phone, and the content distributor can correlate the mobile phone with a television client device that receives television media content from the content distributor. The content distributor can communicate an instruction to configure a client device feature according to the request from the mobile phone. In other embodiment(s), a request for a video clip can be received from the mobile phone, and the content distributor can obtain and communicate the video clip to be rendered on the mobile phone. In other embodiment(s), a request to interface with the content distributor as a diagnostic aid can be received from the mobile phone. The content distributor can execute diagnostic instructions according to the request to identify system problems, and communicate the system problems to the mobile phone as diagnostic feedback. | 12-24-2009 |

20100214703 | POWER DISTRIBUTION SYSTEM USING SOLID STATE POWER CONTROLLERS - Solid state power controllers are described that include a switch controlled by a microcontroller and communication contacts. In one aspect of the invention, the microcontroller is galvanically isolated from the communication contacts using magnetoresistive isolation. In another aspect of the invention a number of solid state power controllers are connected to an external microcontroller to form a power distribution array. In addition, messages exchanged between the external microcontroller and the solid state power controllers can be used to configure the solid state power controllers and provide a user interface. | 08-26-2010 |

20160065179 | HIGH ACCURACY MILLIMETER WAVE/RADIO FREQUENCY WIDEBAND IN-PHASE AND QUADRATURE GENERATION - Certain aspects of the present disclosure provide circuits for generating high accuracy millimeter wave or radio frequency (RF) wideband in-phase (I) and quadrature (Q) oscillating signals having acceptable amplitude and phase mismatch over process, voltage, and temperature (PVT) variations with reduced cost, area, and power consumption. In one example apparatus, a polyphase filter having a first stage and a second stage is provided. Each stage comprises resistive elements and capacitive elements. Certain aspects of the present disclosure provide for intentional resistive and/or capacitive value mismatch between the resistive or capacitive values of one or multiple stages such that the phase mismatch between the resulting I and Q signals may be reduced without degrading the amplitude mismatch. Certain aspects of the present disclosure provide for replacing the resistive elements in at least one stage with transistors operating in the triode region, where the on-resistance is controlled by a feedback network. | 03-03-2016 |
20160099729 | APPARATUS AND METHOD FOR QUADRUPLING FREQUENCY OF REFERENCE CLOCK - A method, an apparatus, and a computer program product are provided. The apparatus outputs a first sinusoidal signal and a second sinusoidal signal according to a first clock frequency, generates, a first digital signal having a 25% duty cycle based on the first sinusoidal signal, generates a second digital signal having a 25% duty cycle based on the second sinusoidal signal, combines the first digital signal and the second digital signal to generate a combined digital signal having a 50% duty cycle and a second clock frequency that is double the first clock frequency, and doubles the second clock frequency of the combined digital signal to generate an output signal having a third clock frequency that is quadruple the first clock frequency. The apparatus further generates a control voltage for the first buffer and the second buffer based on the combined digital signal. | 04-07-2016 |
