| 20150129399 | DEVICES WITH LIQUID METALS FOR SWITCHING OR TUNING OF AN ELECTRICAL CIRCUIT - Devices for switching or tuning of an electrical circuit comprise a liquid metal (LM) drop confined inside a sealed cavity. The cavity is formed at least partially inside a microelectronics layered structure which includes metal, dielectric and semiconductor layers. The microelectronics layered structure may be prepared using a VLSI/CMOS technology. Some of the VLSI/CMOS metal layers or metalized vias may be used for conduction lines contacted by the LM drop or as RF transmission lines opened or closed by the LM drop. | 05-14-2015 |
| 20140069783 | Multiple Droplet Liquid MEMS Component - A liquid micro-electro-mechanical system (MEMS) component includes a board, a channel, multiple liquid droplets, and one or more conductive elements. The channel is within the board and contains the multiple liquid droplets. A first liquid droplet has first properties and a second liquid droplet has second properties. When a force is applied upon the first and second liquid droplets, the first liquid droplet changes in accordance with the first properties with respect to the one or more conductive elements and the second liquid droplet changes in accordance with the second properties with respect to the one or more conductive elements thereby changing one or more characteristics of the liquid MEMS component. | 03-13-2014 |

| 20100025207 | ELECTROSTATICALLY DRIVEN HIGH SPEED MICRO DROPLET SWITCH - An electrostatically driven high-speed micro droplet switch includes a substrate having an upper surface containing one or more signal electrodes that are selectively connected via a droplet. The switch includes at least one actuation electrode disposed beneath the upper surface of the substrate, the at least one actuation electrode operatively coupled to drive circuitry. The switch includes a frame disposed on or above the upper surface of the substrate that is configured to hold the droplet in substantially the same location during operation of the switch. In one aspect, the frame is configured to absorb variations in the volume of the droplet placed on the switch, leaving the active meniscus not affected by the variation in volume. | 02-04-2010 |
| 20110036691 | LIQUID SWITCHES AND SWITCHING DEVICES AND SYSTEMS AND METHODS THEREOF - A dispensing apparatus includes a housing defining a channel, a plunger slidably engaged with an inner surface of the channel, a substrate with one or more passages each having two or more openings, a liquid in each of the one or more passages, at least one fluid, and a force application system. The substrate is disposed in the channel on one side of the plunger. The liquid in each of the one or more passages has a volume which exceeds an internal volume of each the one or more passages and forms a liquid drop around each of the openings. The liquid drops are fluidly connected to one another and each of the liquid drops is individually adjustable between two or more sizes. Each of the sizes and a location of each of the liquid drops define one of two or more switch positions. The fluid is located in the channel on the one side of the plunger and substantially surrounding the liquid drops. The force application system is configured to individually and selectively apply a force on the liquid in each of the one or more passages to control switching between the two or more switch positions of each of the liquid drops. Engaging one or more of the switch positions moves the plunger along the inner surface of the channel away from the substrate. | 02-17-2011 |

PERIODIC | 4 |
| 20080237000 | MICRO SWITCH MOUNTING STRUCTURE AND AUTOMATIC ICEMAKER - A micro switch is mounted onto a mounting base attached to a controller of an automatic icemaker. The micro switch generates a signal for controlling the amount of water to be filled in an ice tray. The micro switch is fixed to the mounting base by the first fixing member and the second fixing member. The first fixing member is inserted through a mounting hole formed in a case of the micro switch. The second fixing member is arranged on a surface of the mounting base on an opposite side of a surface mounted with the micro switch, and is fixed to the first fixing member. | 10-02-2008 |
| 20090152076 | ROTARY SWITCHING DEVICE AND FILE SEARCH SYSTEM USING SAME - The present invention features a rotary switching device and a file search system using the same. In preferred embodiments, the rotary switching device includes a rotary push button, a first switch part, second switch parts, a first contact part, and a second contact part. | 06-18-2009 |
| 20100012470 | Electrical controller - A segmented rotor comprises two disc-like members electrically charged with opposite polarities having circumferentially spaced interleaved fingers extending in an axial direction electrically insulated from one another and rotationally driven by an insulated shaft. Suitable brushes extend radially into contact with the interleaved fingers to produce repetitive alternate polarity electrical signals at each brush as the rotor rotates. The electrical signals are fed to utilization devices to control their operation. | 01-21-2010 |
| 20140166447 | METHOD AND APPARATUS FOR CONTROLLING OPERATIONS AND SIGNALING AT TIMES DEPENDENT ON CLOCK, CALENDAR AND GEOGRAPHIC LOCATION - Techniques are provided for inhibiting changes in the operational state of electrical circuits for lights, appliances and other devices by controlling the effect of manual actuation of an electrical switch in an electrical circuit. A normal mode is established in which manual actuation of the switch effects a change in a state of current flow in the circuit. An alternative holiday mode is also established in which manual actuation of the switch has no effect on current flow in the circuit. Automatic switching occurs between the normal mode and the holiday mode at specific times corresponding to specific events dependent on the time of year, a time of day and a geographic location of the circuit. | 06-19-2014 |

| 20090159418 | Centrifugal Switching Device of Single-Phase Induction Motor - A centrifugal switching device of a single-phase induction motor includes a centrifuge and pressure switches. The centrifuge includes a centrifugal sleeve, a centrifugal base, shaft coupling blocks, and a spring. The spring is directly fitted on the centrifugal base. Under a centrifugal force generated by the rotation of the motor, shaft coupling blocks I and II slide axially against an axial force of the spring, thus forcing an axial end surface of the centrifugal sleeve to be separated from contacts of the pressure switches, such that a starting winding of a stator ferrite-core coil of the single-phase induction motor is disconnected and a heater is turned on. The shaft coupling blocks I and II adopt a design with round transition, central sliding contact, and smooth rotation, thereby achieving a simple structure, convenient mounting, and safety usage. | 06-25-2009 |
| 20110011718 | OPERATING MECHANISM FOR CENTRIFUGAL SWITCH - An operating mechanism for a centrifugal switch contains at least: a terminal box, a cover, a movable contact, a static contact, a swing arm, a reset elastic part, and a shifting fork. The movable contact and the static contact are disposed in the terminal box. The shifting fork operates to drive the swing arm to horizontally swing, whereby pushing the movable contact and implementing connection and disconnection between the movable contact and the static contact. The reset elastic part operates to automatically reset the shifting fork and the swing arm. The invention features reduced requirements for dimensional precision and installation precision of components, and low production cost, and is reliable and durable. In addition, the sliding force is uniformly stressed, which ensures accuracy of operation, easy installation, and high operating reliability. | 01-20-2011 |
