摘要： RFID systems are disclosed that include at least one RFID receiver system and a distributed exciter architecture. The exciters can be connected via wired and/or wireless connections to the RFID receiver system and the RFID receiver system can control the activation of the exciters to detect the presence of RFID tags within interrogation spaces defined by the exciter topology. In several embodiments, the RFID receiver system performs location estimation to determine the interrogation space in which a specific RFID tag or collection of RFID tags is located. One embodiment of the invention includes an RFID receiver system configured to detect information from RFID tags within a receive coverage area, and a plurality of exciters defining a plurality of interrogation spaces within the receive coverage area of the RFID receiver system. In addition, the RFID receiver system is configured to transmit a control signal that identifies one of the plurality of exciters and includes information indicative of an RFID tag interrogation signal, the plurality of exciters are configured to receive the control signal, and the exciter identified in the control signal is configured to illuminate an interrogation space with the RFID tag interrogation signal.

A phase difference of received information signals of illuminated RFID tags is utilized to locate the RFID tags. One or more exciters transmit interrogation signals to illuminate the RFID tags in which the exciters may have a plurality of antenna selectively configured to transmit through two or more antennas and to receive on one antenna. Multiple reads of the same RFID tag can also be performed to generate a probability model of the location of the RFID tag. An enhanced particle filter is applied to probability model to determine the exact location of the RFID.

摘要： There is disclosed a system for sharing power among interconnected tools which is made up of multiple battery-powered tools, each with a battery. Each tool and its battery are electrically connected to a hub, and the hub is adapted to provide charging current to each battery, to monitor the charge level of each battery and to direct current from one battery with a higher charge level to a battery with a lower charge level. The system is also adapted to enable the hub to direct power to corded electric tools.

The reel is positioned within the power cord housing. The reel is rotatably connected to the power cord housing. The power cord is mechanically attached to the reel. The female power outlet is mechanically and electrically attached to the power cord. The switching circuitry is electrically connected to the electrical input. The switching circuitry selectively, electrically connects the electrical input and the power cord. The switching circuitry is electrically connected to the power cord. The controller is communicatively connected to the switching circuitry for controlling the switching circuitry. The controller is also connected to circuitry programmed for regulating the amount of power available to the power cord. The switching circuitry and the regulating circuitry determine whether power is available and how much power is available. The switching circuitry may also be configured to act as a circuit breaker.

摘要： A fan assembly is disclosed. The fan assembly is comprised of a fan with a motor and a blade as to create an airflow, and an actuator which is adapted to move the fan in vertical and horizontal directions, such that the fan directs airflow below it. The fan further comprises a controller adapted to control the adapter, and a remote control which is adapted to control the controller. The remote control sends signals to direct the controller, and both are adapted such that the movement of the fan can be programmed to a path set by a user and can also be manipulated to a static position set by the user. Preferably, the remote control is a smart device, such as a smart phone.

摘要： A method of calibration transfer for a testing instrument includes: collecting a first sample; generating a standard response of a first instrument based, at least in part, on the first sample; and performing instrument standardization of a second instrument based, at least in part, on the standard response of the first instrument. Data corresponding to a second sample is then obtained using the second instrument and a component of the second sample is identified based, at least in part, on a calibration model.
