  • Publication number: 20220083155
    Abstract: The present invention supports the control of a plurality of controlled devices. With three dimensional accelerometer components, detection of a user action on a remote controller and the orientation of the remote controller are viable through small electronic devices. Aspects of the invention are based on the three dimensional accelerometer components to provide a remote controller that can detect the user action. Based on the user action, the remote controller transmits a signal to the controlled device which conveys the corresponding command. A selected controlled device may be matched to the remote controller. The remote controller and controlled device may also support a learning mode, in which the controlled device sends a list of supported commands to the remote controller. The remote controller then matches an associated action with each command in the command list.

  • Patent number: 11170899
    Abstract: Apparatuses and methods detect a health condition of a user that may be assessed from a thermal sensor signal and/or radar sensor signal. One or more resultant biometric vectors may be generated from biometric vectors based on the thermal and radar signals, where the resultant biometric vectors contain resultant information about one or more biometric features for a user. Hazard information about the user is obtained from the one or more resultant biometric vectors, where the hazard information is indicative of a health event for the user. Consequently, an appropriate action on behalf of the user may be performed to ameliorate the health condition. The one or more resultant biometric vectors may include additional biometric features and/or a time sequence of the resultant biometric vectors to enhance hazard prediction. Moreover, the apparatuses and methods may support the user in different settings including a home, business, or vehicle.

  • Publication number: 20210144025
    Abstract: Building blocks for a smart device such as a thermostat include a user interface (UI) unit and a terminal (TML) unit. A UI unit may support one or more input data from a user and/or sensors and/or one or more control terminals. The UI unit may process each input datum or a combination of the input data, generate a control signal to one or more control terminals based on the processing, and send the control signal to one or more control terminals over a communication channel. A terminal unit, which may consist of one or more control terminals, transforms the received control signal into one or more controls to one or more associated environmental generators. One or more UI units may control one or more controlled apparatuses in conjunction with a mobile app to allow a unified user experience.

  • Publication number: 20210143104
    Abstract: An apparatus includes a substrate including an identification code on a first side of the substrate and near a perimeter of the substrate. The apparatus includes a stiffener structure attached to the first side of the substrate. The stiffener structure has a cutout in an outer perimeter of the stiffener structure. The stiffener structure is oriented with respect to the substrate to cause the cutout to expose the identification code. The cutout may have a first dimension and a second dimension orthogonal to the first dimension. The first dimension may exceed a corresponding first dimension of the identification code and the second dimension may exceed a corresponding second dimension of the identification code, thereby forming a void region between the identification code and edges of the stiffener structure.

  • Publication number: 20210055006
    Abstract: A thermostatic radiator valve (TRV) assembly or automatic temperature balanced actuator (ABA) assembly controls a manifold assembly through a push pin bearing mechanism. The push pin bearing mechanism comprises a push pin that moves in a linear direction responsive to rotational movement of a motor gear that is coupled through a helical gear. Rotational movement of the push pin is prevented by a ball bearing assembly. Movement of the push pin is transferred to a manifold pin, which in turn, controls the manifold assembly. Because the push pin moves in a linear rather than a rotational fashion, erosion of the mated manifold pin is substantially reduced with respect to transitional approaches.

  • Publication number: 20210017901
    Abstract: A six-phase thermodynamic cycle for a rotary internal combustion engine. The thermodynamic cycle comprising: Phase 1 (intake) air enters the central intake chamber and mixes with recirculated exhaust gas from phase 3; Phase 2 (low compression) the air and recirculated exhaust gas from phase 1 is compressed at a low compression ratio; Phase 3 (scavenge and recirculation) a portion of air and recirculated exhaust gas from phase 2 scavenges the combustion chamber and partially scavenges the expansion chamber; Phase 4 (high compression) the intake chamber separates to form a compression chamber and the residual combined exhaust gas and air from phase 2 is compressed at a high compression ratio into the combustion chamber; Phase 5 (power phase) an expansion chamber is formed, originating from the static combustion chamber and torque is produced to turn the output shaft; and Phase 6 (exhaust) exhaust gas from phase 5 is discharged.
