    Abstract: A system and method for the commissioning of a lighting system is disclosed. The lighting system includes a plurality of lighting devices and a plurality of locators. Each lighting device includes a light emitting element and a wireless tag. After the lighting system is installed, each lighting device transmits one or more packets that contain a constant tone extension (CTE). This CTE allows the locators to determine the angle of arrival of the incoming packet. By combining the angles of arrival from several locators, it is possible to ascertain the physical location of the lighting device that transmitted the CTE. In this way, the physical location of each lighting device can be correlated to its network address.

    Abstract: A three-way valve is disclosed. The valve achieved constant flow rate as the valve transitions from 100% flow through the first path to 100% flow through the second path. The valve is linearly actuated, which allows a plurality of valves to be efficiently disposed in a manifold. The valve comprises a spool having two passageways therethrough which converge at the input. The spool is disposed in a housing. By linear movement of the spool within the housing, the amount of the incoming flow that passes through each of the two passageways can be controlled. In certain embodiments, the spool is in communication with an actuator to control its position within the housing. The three-way valve may be used as part of a manifold.

    Abstract: An external nonvolatile memory device that includes a rewritable nonvolatile memory and a CMOS interface is disclosed. The interface includes a clock signal which is input to the external nonvolatile memory device. This clock signal is multiplied by an integer to create a memory serdes clock which is used to clock outgoing data. The memory serdes clock is also used to create a clock that is used to clock the incoming data from the main processing device. The external nonvolatile memory device also includes an encryption/decryption block that encrypts data read from the nonvolatile memory before it is transmitted over the interface, and decrypts data received from the interface before storing it in the nonvolatile memory. The encryption/decryption block may utilize a stream cipher.

    Abstract: A system and method for performing production testing on high power semiconductor devices is disclosed. The system includes signal generators, RF meters, sockets, couplers and connectors which also function as switches when connected to an external cable. A calibration process is executed which allows the controller to create a correlation between measurements taken by the RF meter and the actual voltages, and power levels present at the device under test. By performing this calibration, it is possible to perform production testing of devices much more quickly and reliably.

    Abstract: A system having a locator device and a plurality of tag devices is disclosed. The locator device comprises an antenna array allowing it to determine an angle of arrival for incoming signals from each of the plurality of tag devices. The system also defines a sequence of time slots, where each time slot has a specific function. The sequence may start with a locator time slot, where the locator device transmits a packet that informs all of the tag devices that this is the start of the sequence. A sync slot follows the locator time slot, where new tag devices may transmit a sync request to the locator device. Upon receipt of a sync request, the locator device assigns the new tag device a tag slot. Following the sync slot are a plurality of tag slots, where each tag device transmits an AoA packet during its assigned tag slot.

    Abstract: An ion source that may be used to introduce a dopant material into the arc chamber is disclosed. A component containing the dopant material is disposed in the path of an etching gas, which also enters the arc chamber. In some embodiments, the dopant material is in liquid form, and the etching gas travels through the liquid. In other embodiments, the dopant material is a solid material. In some embodiments, the solid material is formed as a porous structure, such that the etching gas flows through the solid material. In other embodiments, one or more components of the ion source are manufactured using a material that includes the dopant material, such that the etching gas etches the component to release the dopant material.
