Patent number: 10972025Abstract: A DC electric motor having a stator mounted to a substrate, the stator having a coil assembly having a magnetic core, a rotor mounted to the stator with permanent magnets distributed radially about the rotor, the permanent magnets extending beyond the magnetic core, and sensors mounted to the substrate adjacent the permanent magnets. During operation of the motor passage of the permanent magnets over the sensors produces a substantially sinusoidal signal of varying voltage substantially without noise and/or saturation, allowing an angular position of the rotor relative the substrate to be determined from linear portions of the sinusoidal signal without requiring use of an encoder or position sensors and without requiring noise-reduction or filtering of the signal.Type: GrantFiled: April 4, 2019Date of Patent: April 6, 2021Assignee: CepheidInventors: Tien Phan, Doug Dority

Patent number: 10529197Abstract: A system is provided that controls an offline haptic conversion. The system receives an input from a source. The system further converts the input into haptic signals. The system further encodes the haptic signals. The system further stores the haptic signals within the source, where the haptic signals are combined with the input within the source. Alternately, rather than encoding the haptic signals and storing the haptic signals within the source, the system handles the haptic signals separately, independent of the source.Type: GrantFiled: March 15, 2018Date of Patent: January 7, 2020Assignee: Immersion CorporationInventors: Robert Lacroix, Satvir Singh Bhatia, Jean-Francois Blanchard-Dionne, Stephen D.

Patent number: 10409380Abstract: A method for dynamically converting an input signal into a haptic signal that causes a haptic output device to output one or more haptic effects is provided. The method includes generating a plurality of effect objects that are orderable in any order at runtime, receiving an input signal including a data signal and metadata defining an order that the effect objects are applied to the data signal at runtime, applying the effect objects to the data signal based on the order, and sending the haptic signal to the haptic output device. The effect objects applied to the data signal include an effect object that determines a threshold magnitude value by mapping the data signal to one of a plurality of bins, and an effect object that applies a dynamic range compression algorithm to the data signal based on the threshold magnitude value.Type: GrantFiled: November 8, 2018Date of Patent: September 10, 2019Assignee: IMMERSION CORPORATIONInventors: Satvir Singh Bhatia, Juan Manuel Cruz Hernandez, Loc Tien Phan
