A stylus (100) is configured for actively interacting with a touch-sensitive interface (201) by injecting or sinking charge in response to a touch-detection signal emitted from the touch-sensitive interface (201). One stylus (100) includes a stylus body (104) and a compound tip (105) extending axially from the stylus body (104). The compound tip (105) can include a center electrode (101) that is configured to detect electric field variations from the touch-sensitive interface (201) and a shroud electrode (102) that is concentrically disposed about the center electrode (101). An active circuit (103) coupled between the center electrode (101) and the shroud electrode (102) is configured to apply a gain to the detected electric field variations and to change a potential of the shroud electrode (102) synchronously with the electric field variations detected by the center electrode (101).

A paint coating system comprises a substrate and a first paint layer disposed on the substrate. The first paint layer is formed from a first composition comprising either a first decomplexing agent or a first organoborane complex. The paint coating system further comprises a second paint layer disposed on the first paint layer. The second paint layer is formed from a second composition comprising the other of the first decomplexing agent and the first organoborane complex. At least one of the first and second compositions further comprises a radical polymerizable compound. A method of producing a multilayered paint coating includes the steps of providing the substrate, applying a first paint layer on the substrate, applying a second paint layer on the first paint layer, and curing the at least one of the first and second paint layers.

A method is provided for abruptly stopping a vibration motor providing tactile feedback (406) to the user of a portable communication device (100). The method comprises providing a drive waveform (401) including an attack signal (402), and a stop signal (411) out of phase with the attack signal (402), to one of the vibration motor (235) or the multi-function transducer (130) to quickly stop the vibration. The drive waveform may include an optional sustain signal (407) subsequent to the attack signal (402) and prior to the stop signal (411). A file stored in memory (212) is accessed to provide the drive waveform (401).
摘要:
A quantum tunneling composite, or other material exhibiting changing electrical or magnetic properties as force on the material is increased, can be located within a force concentrator integrated into traditional touch screen layers to sense force applied on the touch screen. The force concentrator can be a protrusion from the layer planes of the layers in a traditional touch screen and can be formed, at least in part, from printed elements. The amount of protrusion of the force concentrator can be adjusted through multi-pass printing and thicker deposit printing. The force concentrator can also have optically clear adhesive layered over it. The force-sensitive material can be optionally pre-loaded so as to operate within a substantially linear feedback range. A sensing mechanism can be configured to detect changes in force at multiple locations or to detect the application of force irrespective of location.
摘要:
A method of forming a cured coating composition on an automobile component is provided. The method utilizes a coating compound including a radical polymerizable compound and an organoborane initiator and includes the step of applying the coating composition to the automobile component. The organoborane initiator is complexed with a bi-functional noncyclic blocking agent that has a carbon backbone and two organoborane complexing moieties. The two moieties are different from each other and are selected from the group of an amine moiety, a thiol moiety, and a phosphine moiety. In addition, the two moieties are separated from each other by two to four carbon atoms to increase the nucleophilicity of the blocking agent towards the organoborane initiator. The organoborane initiator is decomplexed from the blocking agent thereby forming a radical that is used to polymerize the radical polymerizable compound and cure the coating composition on the automobile component.
摘要:
A capacitive force sensor (100) includes a substrate (101) having at least one electrode pair (102,103) defining a capacitance disposed thereon. The substrate (101) is fixed relative to a first plate (106). A drive circuit (104) is configured to apply a voltage relative to a circuit ground (105) to the electrode pair (102,103). The first plate (106) is separated from a second plate (107) that is coupled to circuit ground (105) by a compliance member (108,109). The compliance member (108,109) is configured to oppose a compression force (110) while allowing the first plate (106) to physically move relative to the second plate (107). A capacitive detection circuit (111) is then configured to detect a change the capacitance when the compliance member (108,109) is compressed. The compression force (110) is then determined from the change in capacitance and the spring constant of the compliance member (108,109).
摘要:
An apparatus (100) including two housings and a piezoelectric transducer is disclosed. The apparatus may include a first housing (110), a hinge (115) coupled to the first housing, and a second housing (140) coupled the first housing via the hinge. The first housing can have a closed position when the first housing is substantially adjacent to the second housing and the first housing can have an open position when a portion of the first housing is substantially away from the second housing. The apparatus can also include a first piezoelectric element (130) coupled to the second housing where the first piezoelectric element can be substantially in contact with the first housing when the first housing is in the closed position. The apparatus can further include a user interface (140) coupled to the second housing and a controller (150) coupled to the first piezoelectric element and the user interface. The controller can drive the first piezoelectric element to cause the first housing to vibrate against the second housing when the first housing is in the closed position. The controller can also drive the first piezoelectric element to provide tactile feedback in response to user activation of the user interface.
