Abstract: Embodiments of the present invention are directed to a portable insertion medical device (also referred to as “self-collection insertion plunger device” or “self-collection delivery plunger device”) with the design of a brush body for self-collection of a plurality of specimens from female genitalia. In one embodiment, the self-collection insertion plunger device includes a brush portion having a plurality of bristles that expand outward with a tensile strength to collect a plurality of specimens after insertion for a predetermined amount of time. In another embodiment, the self-collection insertion plunger device has a brush body with a plurality of petals and a plurality of bristles for a wider coverage in the collection of a plurality of specimens, particularly as the plurality of petals expand after insertion into female genitalia.

Abstract: Methods and apparatuses for direct multiplication Fourier transform millimeter wave spectroscopy are disclosed herein. A sample method includes generating at least one pulse of microwave electromagnetic energy. The sample method also includes frequency-multiplying the pulse(s) to generate at least one frequency-multiplied pulse and filtering at least one spurious harmonic of the frequency-multiplied pulse to generate at least one filtered pulse. The spurious harmonic is generated by frequency-multiplying the pulse. The method also includes exciting a sample using the filtered pulse. The method further includes detecting an emission from the sample. The emission is elicited at least in part by the filtered pulse.

Abstract: Apparatus and techniques for broadband Fourier transform spectroscopy can include frequency hopping spread-spectrum spectroscopy approaches. For example, an excitation source power can be spread over a specified frequency bandwidth, such as by applying a sequence of short, transform-limited pulses to a sample. Each pulse can include a specified carrier frequency, and a corresponding bandwidth of the individual pulse can be determined by a frequency domain representation when Fourier transformed. A series of short excitation pulses can be used to create an excitation sequence, such as to deliver a specified or desired amount of power to the sample, such as by having the excitation source enabled for a time comparable to a free induction decay (FID) dephasing time.

Abstract: A backpack for carrying an item by a user includes a backpack body constructed of a flexible material. A first zipper fastener is on the backpack body and is actuatable between an opened position and a closed position. The backpack includes an accessory body constructed of a flexible material and positioned within an inner main cavity of the backpack body and borders an exterior of the backpack. The backpack includes a second zipper fastener on a first portion of the accessory body that borders the exterior of the backpack. The second zipper fastener is actuatable between an opened position and a closed position. The backpack includes a third zipper fastener on the second portion of the accessory body that borders the inner main cavity of the backpack body. The third zipper fastener is actuatable between an opened position and a closed position.

Abstract: Examples herein include apparatus and techniques that can be used to perform rotational spectroscopy on gas-phase samples. Such techniques can include using a spectrometer providing frequency synthesis and pulse modulation to provide excitation (e.g., pump or probe pulses) of a gas-phase sample at mm-wave frequencies. Synthesis of such mm-wave frequencies can include use of a frequency multiplier, such as an active multiplier chain (AMC). A free induction decay (FID) elicited by the excitation or other time-domain information can be obtained from the sample, such as down-converted and digitized. A frequency domain representation of the digitized information, such as a Fourier transformed representation, can be used to provide a rotational spectrum.

Abstract: An electric vehicle battery pack including a plurality of batteries ganged together in an underlying tray. The tray preferably has a plurality of pockets therein each for receiving an individual battery. The batteries are interlocked one to the next and held in place in the tray by a housing which bears down on the batteries by means of a resilient spacer positioned between the tops of the batteries and the ceiling of the housing. The pack forms a structural part of the vehicle in which it is used.
