Abstract: A medical gown includes tie straps detachably connected to sleeves of the gown. The straps are detachable by tugging on them once the gown is donned. The tie members are extendable, upon being detached, around the left and right sides to a back of the medical gown for tying together to form a closure around a waist of a wearer. The tie members may be sufficiently long to extend back around for tying in the front of the gown. A section of each of the left and right tie straps may be folded over lengthwise, a portion of the folded section of each tie member being detachably connected to the sleeves. Once the wearer detaches the folded tie members, the tie members may be unfolded and elongated as needed for adjustably sizing the closure securing the medical gown on the wearer.

Abstract: An apparatus with structures in a conductive film that let a selected set of RF frequency bands pass through, while blocking the passage of all other frequencies is disclosed. The film may include a first portion of the film and a second portion of the film circumscribing the first portion. The second portion is separated from the first portion by a first gap along a periphery of the first portion of the film and wherein a width of the first gap is associated with a wavelength of a first radio signal.

Abstract: A lightweight deployable antenna assembly for, e.g., microsatellites including multifilar (e.g., quadrifilar) antenna (MHA) structures rigidly maintained in an array pattern by a lightweight linkage and collectively controlled by a central antenna feed circuit and local antenna feed circuits to perform phased array antenna operations. The linkage is preferably an expandable (e.g., flexural-scissor-grid) linkage capable of collapsing into a retracted/stowage state in which the MHA elements are maintained in a closely-spaced (e.g., hexagonal lattice close-packed) configuration optimized for payload storage. To deploy the antenna for operation, the linkage unfolds (expands) such that the MHA elements are moved away from each other and into an evenly spaced (e.g., wide-spaced hexagonal) pattern optimized for phased array operations. The MHA structures utilize modified helical filar elements including metal plated/printed on polymer/plastic beams/ribbons, or thin-walled metal tubes.

Abstract: A system of sensor nodes is combined with an RF hub that transmits RF power to the sensors and receives data therefrom. The sensor nodes contain: one or more sensors for measuring indoor conditions, an antenna, an energy storage element, and electronics for powering the system via harvesting RF energy, reading sensor data, and communicating sensor data. The sensors, antenna, and other components on the nodes can be fabricated conventionally, or via printing. They may be fabricated as “flexible hybrid electronics”, in which conventional components are bonded onto flexible substrates. The RF hub consists of one or more antennas capable of transmitting RF power electronics for steering the center of radiation of the RF power in at least one direction or in more than one direction electronics for receiving a demodulating RF data signal. The RF hub may be powered directly from the building.

Abstract: A radio frequency (RF) energy harvesting device including a scalable metamaterial resonator antenna and a rectifying circuit formed on a flexible plastic substrate. The metamaterial resonator antenna includes a metal (e.g., silver) structure that is conformally fixedly disposed (i.e., either printed or deposited/etched) on the flexible substrate and configured to resonate at RF frequencies using primary and secondary antenna segments connected by linking segments such that captured RF signals are generated at two antenna end points that are 180° out-of-phase with each other. The rectifying circuit including additional metal structures that are also printed or otherwise formed on the flexible substrate, and one or more circuit elements that are configured to pass positive voltage pulses from the captured RF signals to an output node. Various metamaterial resonator antenna configurations are disclosed.

Abstract: A radio frequency (RF) energy harvesting device (rectenna) includes an antenna structure configured to resonate at RF frequencies, and a rectifying circuit that facilitates harvesting multiband RF signals having low energy levels (i.e., tens of mW and below) by utilizing two Zero Bias Schottky diodes having different forward voltage and peak inverse voltage values. Positive voltage pulses from a captured RF signal generated on a first antenna end point are passed by the first diode to a first internal node where they are summed with a second RF signal generated on the second antenna end point (i.e., after being passed through a capacitor), thereby producing a first intermediate voltage having a substantially higher voltage level. Positive voltage pulses are then passed from the first internal node through the second diode to an output control circuit for conversion into a usable DC output voltage.

Abstract: A camera shield system includes a vehicle that has a back side. At least one camera is coupled to the back side. The at least one camera may display an area behind the vehicle when the vehicle is backing. Thus, the vehicle may avoid striking an object when backing. At least one cone is provided. The at least one cone is coupled to the back side and the at least one cone is positioned to surround the at least one camera. Thus, the at least one cone inhibits the at least one camera from becoming obstructed with precipitation.

Abstract: A self-adjusting passive radiative cooling panel for spacecraft including a dielectric (e.g., HfO2) layer sandwiched between a mirror layer and spaced-apart thin-film phase-change (e.g., thermochromic) material islands disposed in a grating pattern having a lattice constant in the 2 to 10 ?m range, depending on expected spacecraft operating temperatures. At low temperatures the phase-change material islands enter dielectric state phases that prevent generation of guided modes in the dielectric layer resulting in zero or low mid-IR emission. At high temperatures the phase-change material islands enter a metal state phase that couples mid-IR (thermal) radiation to guided mode resonances resulting in high mid-IR emission. The thermal emission can be tuned by the lattice constant of the grating pattern to peak at a target mid-IR wavelength (e.g.

Abstract: A medical gown includes a self-adjusting strap(s) that expands an upper torso section beyond a nominal girth thereof, for an adjustable fit. An upper and lower self-adjusting strap may be provided across the back. The straps may be formed from perforations in the upper torso section. A portion of the gown breaks away along the perforations to form the straps in response to stress or pulling when donned or during use. The self-adjusting straps allow expansion of the upper torso section to conform to users who require larger than the nominal girth, while continuing to secure the medical gown on the wearer during use. Extendable tie straps may be included, which are unfolded and elongated for adjustably sizing the closure around the wearer's waist. The tie straps may be sufficiently long to extend to the back, and back around the waist again for tying in the front of the gown.

Abstract: An apparatus, computer-readable medium, and computer-implemented method for creating collateralized portfolios. A portfolio is a collection of income-producing assets. These income-producing assets are a derivative of primary sources such as real property. A portfolio is generated through transactions that exchange estimated asset value for liquid instruments in the portfolio. Asset valuation is determined through known pricing functions. Transaction elasticity is provided by liquid instruments (reserve funds and portfolio-owned shares) held in reserve in the portfolio's reservoir which provides a market smoothing function to gracefully adapt to changes in asset demand and risk. Each portfolio's reservoir is collectively owned by the shareholders; continuously replenishing itself with income generated by assets in the portfolio.

The set of electrical signals generated by the sensor elements of the sensor unit represents a measured signature of the environment in the vicinity of the sensor unit. An analyzer is configured to extract the measured signatures of each sensor unit from sensor unit information signals and to detect a presence and concentration of one or more of the gases of interest based on the measured signatures.

Abstract: A device includes a phase shifting element array comprising a plurality of metamaterial structures that resonate in response to an input electromagnetic (EM) signal. The phase shifting element array generates an output EM signal that is a sum of component output electromagnetic signals generated respectively by the metamaterial structures and is configured to propagate wirelessly through at least a portion of a patient's body. A control circuit controls one or both of phases and amplitudes of the component electromagnetic output signals so that at least one of constructive and destructive interference between the component output electromagnetic signals causes the output signal to have a higher intensity EM radiation at a target region interior to the body and to have a zero or low intensity radiation at a non-target region interior to the body.

Abstract: The intent is to improve the usability of a kitchen sink dishpan by the added utility of a built in or produced drain hole in the dishpan. There are discrete embodiments employed in concert with the drain hole, any of which improve the usability, utility and marketability of a kitchen sink dishpan. This drain hole in the dishpan is centered over the kitchen sink drain as the dishpan resides in the kitchen sink The drain hole can be sized to accommodate a rim and basket sink strainer. Or the drain hole can be sized rather to accommodate a cup strainer with sink stopper. Or the drain hole can be sized rather to accommodate a sink stopper alone. Each of these discrete installations is successful in alternately sealing and unsealing the dishpan drain hole. This allows the dishpan to hold or drain the dishwater saving the user the trouble of lifting and dumping the contents. Hence the term, the “Drain Dishpan.
