Abstract:
Mechanically heated and cooled clothing with easy-to-use controls is provided. An embodiment comprises an athletic shoe with temperature controls and electrical wiring. A heating and cooling unit attached to the shoe comprises a thermostat, a cooling device, and a heating device. Temperature transfer means in the shoe, such as electrical heating elements and loops for liquid heat exchange, accomplish desired heating and cooling of the shoe. The temperature controls may comprise on, off, hot, and cold buttons for activating the heating and cooling unit and controlling the temperatures. The system may be attached to the shoe or attached to other items and worn elsewhere, such as to a belt worn about the user's waist. The system may also be used with other types of clothing, for example with gloves.
Abstract:
An optically-triggered silicon controlled rectifier (SCR) device (21) mounted on a lead frame (34). The SCR device contains a cathode layer (24), an optical gate or control layer (23), and an anode layer (31) formed on a semiconductor substrate (22). The device is soldered onto a pedestal (33) formed on the lead frame. To connect the device to the lead frame, solder is deposited upon the anode layer and the solder fixes the anode layer to the pedestal on the lead frame. The pedestal may be formed by etching or stamping a depression (35) in the lead frame. The device is centered on the pedestal such that the edges of the device are located adjacent the depression, and are spaced from the lead frame.
Abstract:
Embodiments provide for decoupling a module that assigns a SPAM confidence level from a module that executes actions within a message rule, and allowing a user the flexibility in assigning those actions. The confidence level indicates the likelihood that a received message includes unsolicited or unwanted content and is assigned to a received message by a calculation module. A rule execution module accesses an Anti-SPAM rule, which includes conditions and actions defined by a user. The rule execution module then scans the message to determine if the conditions are met and what actions should be executed. For example, a condition of the Anti-SPAM rule may be a threshold value, which is compared to the SPAM confidence level. If the SPAM confidence level exceeds the threshold the actions within the Anti-SPAM rule are executed.
Abstract:
An optically-triggered silicon controlled rectifier (SCR) (21) having a number of semiconductor layers (23, 24, 31) diffused into an N type substrate (22). Specifically, the SCR is formed by diffusing a first P+ layer (23) into an upper surface of the substrate. Then, an N+ layer (24) is diffused into a portion of an upper surface of the first P+ layer. An oxide layer (25) which is permeable to optical radiation is formed on the first P+ layer. A conductive cathode terminal (26) is then deposited on the N+ layer. Therefore, a trench (30) is etched in the lower surface of the substrate. The trench is defined by a depth and a surface. A second P+ layer (31) is diffused into the surface of the trench. The depth of the trench substantially defines a spacing between the first and second P+ layers. The chip is soldered onto a pedestal (33) formed on a lead frame (34). The solder is deposited in the trench and contacts the second P+ layer to form an anode terminal (36). The pedestal may be formed by either etching or stamping a depression (35) in the lead frame.
Abstract:
A method of making a monolithic structure for an optocoupler that provides improved linearity. The method includes forming an output signal photodiode and a feedback control signal photodiode on a single chip with an LED. The photodiodes are configured and positioned relative to the LED to compensate for any non-uniformities in the light received from the LED.
Abstract:
A data access arrangement (DAA) having a transhybrid circuit for separating a transmit signal from a received signal by providing a transmit cancellation signal to the inverting input of a servo-feedback differential amplifier on the receive channel of the DAA. The cancellation signal is provided by a photodiode optically coupleable with a light emitting diode within a optical isolator on the transmission channel of the DAA. The gain of the cancellation signal can be independently controlled.
Abstract:
A router guide comprising a channeled track with a fixed fence attached at a top surface of a first end and a moveable fence slideably attached between the first end and the second end. The track affixes to one side of the workpiece and a router attached to a circular disk is manually slid between the fences to cut slots in the workpiece. The fences are rotatable to a plurality of angles to the track. A pair of router stops may be attached to the fences to limit the sliding motion of the router.
Abstract:
Embodiments provide for storing message rules in a serialized global form on a server for transfer of the data between different servers. Message rules include condition and action data structures, wherein at least the action data structures include global identifiers. A client creates a message object that includes an extended rule with the global identifiers, sets a property on the message object used to identify the object as an extended rule, serializes the message object using a code library, and stores the message object on a message server. Upon execution of a message rule, the rule is deserialized using a copy of the code library and translated into server specific for executing the extended rule on received messages.
Abstract:
An electrically-conductive grid placed between an LED and a photodiode prevents false triggers of the photodiode by transient electrical fields. The grid terminates the field but allows light output of the LED to pass to the photodiode.
Abstract:
A monolithic optocoupler having a light emitting diode for emitting light, a first photodiode for producing a current based on light sensed by it, a second photodiode for producing a current based on light sensed by it and an insulator for electrically isolating the light emitting diode from the first photodiode. The insulator is substantially transparent to light emitted by the light emitting diode. The first and second photodiodes are positioned with respect to the light emitting diode such or that directional non-uniformities of light emitted by the light emitting diode are compensated.
