Abstract: The combination of active and reference haptics on an electronic device, such as a wearable display device, can convey information to a user without requiring the user to look at the device. An electronic device may include a housing, a display disposed in the housing and including an interface surface arranged for user contact and a reference haptic. The interface surface includes an active haptic output that provides a time-dependent haptic output and a reference haptic disposed on the housing or the interface surface to provide a time-independent haptic output related to the time-dependent haptic output.

Abstract: An electronic device may include a housing (100), a display (102) disposed in the housing (100) and including an interface surface (112) arranged for user contact and a reference haptic (108). The interface surface (112) includes an active haptic output that provides a time-dependent haptic output and a reference haptic (108) disposed on the housing or the interface surface to provide a time-independent haptic output related to the time-dependent haptic output. The combination of active and reference haptics on an electronic device, such as a wearable display device, can convey information to a user without requiring the user to look at the device.

Abstract: A high-temperature-resistant casting system comprises following casting elements in a connection relationship: a sprue cup (1) and a down sprue (2) connected with a lower end of the sprue cup, wherein the other end of the down sprue is connected with one end of a filtering element (6), the other end of the filtering element is connected with a three-way pipe (3), openings in two sides of the three-way pipe are connected with one end of an inlet section of a runner (4), and one end of an outlet section of the runner is connected with a tapered elbow (5). The casting elements comprise the following components in percentage by weight:41-51% of a refractory fiber, 40-51% of a silicate fiber and 5-19% of a binder. A preparation method of the high-temperature-resistant casting system is further provided.

Abstract: Disclosed herein are techniques and systems for providing simulated, haptic feedback that is local to physical, non-actuating keys of a keyboard. A keyboard includes a plurality of non-actuating keys defined in a cover portion of the keyboard, a plurality of force-producing mechanisms coupled to a substrate underneath and adjacent the cover portion. The force-producing mechanisms may be positioned on suspended portions of the substrate that are mechanically isolated and arranged on the substrate to substantially correspond to a layout of the plurality of non-actuating keys. The force-producing mechanisms may be individually actuated to deflect the suspended portions of the substrate underneath the cover portion to create a tactile sensation for a user's finger that is local to a particular key. In some embodiments, the force-producing mechanisms are piezoelectric actuators.
