20110167992 | Method and Apparatus for Multi-Touch Sensing - The method and apparatus for multi-touch sensing is capable of detecting multiple musical instrument inputs and gestures. For example, a hand drummer may play with multiple fingers on one hand while using the heel of the palm of the other hand to slide across the drumming surface increasing the force on the head and modify the pitch of the drum. The method and apparatus for multi-touch sensing simulates conventional drum playing surfaces using multi-entry input and enables the gestural features of conventional drum playing surfaces. | 07-14-2011 |
20120097009 | Hybrid Drum - A hybrid drum as described combines the characteristics of both acoustic and electronic percussion apparatus enabling a musician to have a single instrument and have either acoustic or electronic output. A hybrid drum includes a multilayer drum head with a built-in FSR sensor such that the FSR drum head replaces the drum head of the acoustic drum and can be used to perform acoustically and or electronically. The FSR sensor is built into a double layer, double-head acoustic drum head, wherein one layer of the double head system has the FSR element printed on it, while the other layer of the double layer head has the inter-digiting conductive fingers printed on it and facing the FSR element. A conductive tail extends from one of the drum head layers and is operably connected to an electronic module secured to the drum shell. | 04-26-2012 |

20130167663 | Hybrid Capacitive Force Sensors - Hybrid force sensitive input devices are formed as a membrane assembly that is capable of detecting capacitive presence near the sensor surface as well as pressure inputs and varying applications of pressure to the sensor surface. As a capacitive sensor, the electrical charge of a user's hand, finger or other extremity is sensed by the conductive layers of the sensor as a function of the input extremity's location and proximity to the sensor surface. As a force sensor, a user's input contact with the sensor surface is detectable when conductive elements on apposing substrates are forced into contact when input force is applied. Increasing the applied force increases the number of conductive particles making contact allowing the electrons to travel from one conductive trace on a first substrate through the contacting conductive patches to a perpendicular conductive trace on a second substrate. | 07-04-2013 |
20130340598 | Impact Responsive Portable Electronic Drumhead - A portable electronic drumhead includes a sensor responsive to drumstick impacts in producing electrical signal pulses input to headphones to thereby simulate sounds of an acoustic drumhead. The sensor includes a Force Sensing Resistor (FSR) lamination coated with an electrically conductive polymer ink, a spacer lamination, and a flexible electrode lamination having on an inner surface thereof a pair of interdigitated electrodes, the electrode lamination elastically contacting the FSR lamination in response to drumstick impacts on the outer surface of the electrode lamination or FSR lamination to thus momentarily reduce electrical resistance between the electrodes. Resilient batter pads overlying the laminations muffle sounds produced by drumstick impacts. Optionally, the sensor may have an annular ring shape which may be placed concentrically on the head of an acoustic drum, the sensor having an upwardly protruding resilient bumper strikable to produce electronically synthesized rim shot sounds. | 12-26-2013 |
20140083207 | Pre-Loaded Force Sensors - Pre-loaded force sensitive input devices, force sensing resistors (FSR), are formed as a multiple membrane assembly that is capable of detecting low intensity pressure inputs and quantifying varying applications of pressure to the sensor surface. Pre-loading the force sensor elements results in controlled amount of force between the two substrates causing a constant state of pre-load and eliminating the low-end or minimal pressure signal noise associated with unloaded sensors. Pre-loading the force sensing resistor sensors also enables the sensor to detect removal of low intensity pressure input such as might occur during theft of light weight articles placed in contact with the pre-loaded force sensor. Using an FSR or FSR Matrix Array will enable any handling of protected retail packaging to be detected and identified. A library of “touches” can be established that will yield cutting, ripping, twisting, etc. making the detection of a theft in progress more accurate. | 03-27-2014 |
