An electronic device with a force sensing device is disclosed. The electronic device comprises a user input surface defining an exterior surface of the electronic device, a first capacitive sensing element, and a second capacitive sensing element capacitively coupled to the first capacitive sensing element. The electronic device also comprises a first spacing layer between the first and second capacitive sensing elements, and a second spacing layer between the first and second capacitive sensing elements. The first and second spacing layers have different compositions. The electronic device also comprises sensing circuitry coupled to the first and second capacitive sensing elements configured to determine an amount of applied force on the user input surface. The first spacing layer is configured to collapse if the applied force is below a force threshold, and the second spacing layer is configured to collapse if the applied force is above the force threshold.

Force sensing architectures

Disclosed herein are methods and systems for providing haptic output on an electronic device. In some embodiments, the electronic device includes an actuator configured to move in a first direction. The electronic device also includes a substrate coupled to the actuator. When the actuator moves in the first direction, the substrate or a portion of the substrate, by virtue of being coupled to the actuator, moves in a second direction. In some implementations, the movement of the substrate is perpendicular to the movement of the actuator.

Contracting and elongating materials for providing input and output for an electronic device

A haptic electromagnetic actuator for track pad is provided. The actuator includes an array of electromagnets with alternating South and North poles on a first end, each magnet comprising a metal core and an electrical wire around the metal core. The array of magnets is coupled to a base plate on a second end opposite to the first end. The actuator also includes an attraction plate at a distance from the first end of the array of the magnets such that the attraction plate moves toward the magnets when an electrical current flows through the electrical wire around the metal core and moves away from the magnets when the current becomes zero. The array of magnets is configured to form a uniform gap from the attraction plate.

Haptic electromagnetic actuator

An optical force sensor that may compensate for environmental effects, including, for example, variations in temperature of the device or the surroundings. In some examples, two force-sensitive layers are separated by a compliant layer. The relative electrical response of the two force-sensitive layers may be used to compute an estimate of the force of a touch that reduces the effect of variations in temperature. In some examples, piezoelectric films having anisotropic strain properties are used to reduce the effects of temperature.

Temperature compensating sensor having a compliant layer separating independent force sensing substrates and sense circuitry to obtain a relative measure between the force sensing substrates

An optical force sensor, which may be used as input to an electronic device. The optical force sensor may be configured to compensate for variations in temperature using two or more force-sensitive components that are formed from materials having different temperature- and strain-dependent responses.

Temperature compensating force sensor

An electronic device including a processor, a display screen in communication with the processor, a track pad in communication with the processor including a movable surface that is selectively movable in at least one direction to provide feedback to a user, and a feedback system in communication with the processor including a feedback sensor. The feedback sensor determines a movement characteristic of the movable surface and the processor selectively adjusts at least one setting of the track pad based on the movement characteristic.

Calibration of haptic feedback systems for input devices

A haptic feedback assembly includes interconnections for mechanically and electrically securing a haptic actuator in a track pad assembly so as to securely and efficiently provide haptic feedback to a user.

Haptic feedback assembly

Noise in sensor panel measurements can be reduced using a common pixel correction algorithm. Noise can be introduced into touch or force sensor panel measurements, for example, by circuitry of a transmit (Tx) section or a receive (Rx) section coupled to one or more sensing nodes of a sensor panel. For example, a digital-to-analog converter in the transmit section or an analog-to-digital converter in the receive section can introduce low-frequency correlated noise. Additionally, transmit and receive sections can introduce uncorrelated noise into the system. Reference nodes, coupled between Tx and Rx sections, can sense correlated and uncorrelated noise from the Tx and Rx sections. The noise measured at reference nodes can be subtract from signals measured at other sensing nodes coupled to the same Rx channel. The measurement at the reference node can be scaled using a scaling parameter to account for differences between reference nodes and sensing nodes.

The disclosed embodiments provide a method and system for processing data. During operation, the system obtains a set of records, wherein each of the records comprises one or more metrics and at least one dimension associated with the one or more metrics. Next, the system creates a data segment comprising at least one of a forward index and an inverted index for a column in the records. The system then stores the data segment in network-accessible storage and assigns the data segment to a partition. Finally, the system enables querying of the data segment through a query node associated with the partition.

Management of data segments for analytics queries

The disclosed embodiments provide a system that processes data. During operation, the system obtains a set of records, wherein each of the records comprises one or more metrics and at least one dimension associated with the one or more metrics. Next, the system creates, in a data segment comprising the records, an inverted index for a column in the records based on a cardinality of the column. Finally, the system compresses the inverted index based on a jump value associated with record identifiers in the column.
