Abstract: An electric power apparatus includes a main planar body having a circular opening that supports a brushless direct-current (BLDC) motor. The motor includes a stator, a rotor, a motor spindle extending through the circular opening, a first end cap formed on a first side of the stator and mounted on the main planar body; and a second end cap formed on a second side of the stator and secured to the first end cap to form a substantially watertight seal around the stator and the rotor. A ratio of a maximum power output of the motor when powered by at least one battery pack to a height of the motor as measured from an upper surface of the main planar body to a top surface of the motor is greater than or equal to approximately 34 watts/mm.

Abstract: An electric motor is provided including a stator, a rotor, a motor spindle coupled to the rotor and extending along a center axis, a first end cap formed on a first side of the stator, a second end cap formed on a second side of the stator and secured to the first end cap to form a first compartment around the stator and the rotor, an electro-magnetic brake module disposed on a side of the second end cap opposite the stator and engaged with the motor spindle, and a motor cover mounted on the second end cap to form a second compartment around the electro-magnetic brake module. The first end cap, the second end cap, and the motor cover form a substantially watertight seal around the stator, the rotor, and the position sensor assembly.

Abstract: Described herein are methods which involve minimizing or eliminating the occurrence of delayed negative effects that may arise from exposure to reduced oxygen partial pressure. An amount of supplemental oxygen, which substantially mimics a target oxygen partial pressure, is administered to an individual that is exposed to a reduced oxygen partial pressure environment, to compensate for the reduced oxygen partial pressure. The target partial pressure may be selected such that the individual experiences substantially no change in the oxygen partial pressure. Individuals receiving the supplemental oxygen may be healthy, have special sensitivities, or have a pre-existing neurological condition.

Abstract: A grit removal unit including a cylindrical grit removal chamber above a grit storage chamber, with an opening to the grit storage chamber through the grit removal chamber bottom. At least one layer plate is an inverted truncated cone around the center axis which is spaced from the grit removal chamber vertical wall to allow fluid flow therebetween. Concentric inverted truncated cone lamella plates are supported in the grit removal chamber above the layered plates, with the lamella plates radially spaced from one another relative to the center axis. An influent opening in the grit removal chamber vertical wall below the layered plates allows fluid and grit into the grit removal chamber, and an effluent opening in the grit removal chamber vertical wall above the lamella plates allows fluid to exit the grit removal chamber.

Abstract: Systems and associated methods for detecting a set of spectrum sensing falsification (SSF) attacks in a geographic database (GDB) driven cognitive radio (CR) system. Viewing the GDB as a type of non-orthogonal compressive sensing (CS) dictionary, the composite power spectral density (PSD) estimate at a candidate CR is approximated by a small number of sensor nodes listed in the GDB. In a dense CR network, the PSD estimate at a CR may contain a composite mixture of spectrally overlapping signals. An implementation of an optimized, greedy algorithm orthogonal matching pursuit (OMP) returns a set of sensor nodes which are suspected to be in the vicinity of the CR. A sufficient match between the PSD estimate reported by a candidate CR and the PSD that is sparsely approximated from the SNs in its area provides confidence (trust) metrics which may be used to detect potential SSF attacks.

Abstract: An adjustable plant support is disclosed. The support includes an upright support, a plurality of holes disposed along a length of the upright support, and at least one support arm configured to be removably secured to the upright support through a selected hole of the plurality of holes. The support arm also includes a hook at a distal end of the support arm and is configured to define an interior portion of the support arm and adapted to support a plant. A pin of the support arm is at a proximate end of the support arm, where a free end of the pin is configured to slidingly engage the selected hole. In addition, the pin of the support arm extends back towards the U-shape collar in a different lateral plane, where a width of the U-shaped collar is configured to slidingly engage an outer surface of the upright support.

Abstract: Viewing a three dimensional area from numerous camera angles at different exposures using intensity and chromaticity data at the different exposures to create a pixel model for each pixel. A current image is compared with the background model to find pixels that have changed from their pixel model. These novel pixels are processed using contiguous region detection and grouped into foreground figures. For each camera, software extracts features from each foreground figure. A central processor maintains an object model for each foreground figure. A graphical user interface displays the relative location of foreground figures in a world model. The location and identification of the foreground figures is checked against a table of permissions so as to selectively generate an alert. If a figure leaves or is about the leave a cell, the invention accounts for its approximate position and notifies adjacent cells of the expected arrival of the foreground figure.

Abstract: Techniques are disclosed for detecting, identifying, and/or geolocating RF communications devices, such as FRS radios, high-power cordless phones, cellular phones, and other wireless communications receiver devices. The techniques exploit a vulnerability present in such devices, and can be used to detect (e.g., up to 300 meters) and geolocate (e.g., within +/?3 meters) those devices. The vulnerability is that receiver circuitry of the target devices emanate RF mixing products when flooded with RF energy or suitable stimulus signal. Such a response to a stimulus signal is unexpected or otherwise unintentional, as receiver circuitry is generally not designed to transmit information. The RF frequency, phase, and amplitude of these sideband RF responses can be used to detect and location the devices. The techniques work in the presence of interference, and can be used on devices that are powered on or off.

Abstract: Techniques are disclosed that allow for the detection, identification, direction finding, and geolocation of emergency personnel in a given multipath environment. For example, the techniques can be used to detect and identify multiple lines of bearing (LOBs) to an IEEE 802.11 emitter of an emergency responder that is inside a building or otherwise hidden from view. LOBs from multiple vantage points can be used to geolocate and/or track the emergency responder. The resulting geolocation can be plotted on a map display or model of the scene (e.g., building, etc) so the precise position of the emergency responder having the targeted wireless emitter can be known.

Abstract: Techniques are disclosed that allow for the detection, identification, and direction finding of wireless emitters in a given multipath environment. For example, the techniques can be used to detect and identify a line of bearing (LOB) to an IEEE 802.11 emitter in a building or in an open field or along a roadside. In some cases, multiple LOBs can be used to geolocate the target emitter if so desired. The techniques can be embodied, for instance, in a handheld device that can survey the target environment, detect an IEEE 802.11 emitter and identify it by MAC address, and then precisely determine the LOB to that emitter. In some cases, a sample array of response data from the target emitter is correlated to a plurality of calibrated arrays having known azimuths to determine the LOB to the target emitter.

For example, the techniques can be used to detect and identify a line of bearing (LOB) to an IEEE 802.11 emitter in a building or in an open field or along a roadside. Multiple LOBs computed from different geographic locations can be used to geolocate the target emitter. The techniques can be embodied, for instance, in a vehicle-based device that can survey the target environment, detect an IEEE 802.11 emitter and identify it by MAC address, and then determine various LOBs to that emitter to geolocate the emitter. In some cases, a sample array of response data from the target emitter is correlated to a plurality of calibrated arrays having known azimuths to determine the LOB to the target emitter.
