Abstract: Methods and systems for analyzing a sample and generating a predictive model using cavity ring-down spectroscopy are disclosed. At least part of a sample is loaded in a ring-down cavity. For each of a set of wavelengths, a laser beam is generated and directed into the ring-down cavity. The laser beam entering the ring-down cavity is extinguished. Light intensity decay data for light exiting the ring-down cavity is registered via a light intensity sensor system. A probability is determined from the light intensity decay data for the set of wavelengths that a subject from which the sample was received has a physiological condition or a degree of the physiological condition at least indirectly using a dataset of light intensity decay data for previously analyzed samples for which the presence or the absence of the physiological condition or the degree of the physiological condition have been identified.

Abstract: A bicycle includes a front wheel and a rear wheel and a frameset supported on the front wheel and the rear wheel. The frameset includes a main frame and a front fork rotationally coupled to the main frame. The main frame includes a top tube, a head tube rotationally supporting the front fork, a down tube coupling the head tube to a bottom bracket, a seat tube extending downward from the top tube and including a lower end spaced from the bottom bracket, a seatstay extending rearward from the lower end of the seat tube, and a strut member extending forward from the lower end of the seat tube and connecting the seat tube to the down tube.

Abstract: A bicycle includes a frame having cross sectional profiles. The profiles are designed according to certain criteria to enhance bicycle performance. The profiles for multiple frame members may each fall within a range for each of aspect ratio, circumference, drag coefficient, first moment of inertia and/or second moment of inertia.

Abstract: A device detects a trigger to dispense a product at a dispense point using a tool operably coupled to a tractor. In response to detecting the trigger, the device determines a delay time between commanding the tool to dispense the product and the product actually being dispensed, and determines a release point based on operating parameters of the tractor, the release point being a point at which the tractor is predicted to be an amount of time away from the dispense point equal to the delay time. The device determines that the tractor has reached the release point, and commands the tool to dispense the product, where the product reaches the dispense point based on the delay time.

Abstract: Systems and method for retaining a downspout onto a spout are disclosed. The downspout may be retained on the spout using hook and loop fasteners. In some implementations, a portion of a spout may include a first portion of a hook and loop fastener and the downspout may include a second portion of the first hook and loop faster. The first and second portions of the hook and loop faster are complimentary such that the first and second portions of the hook and loop fastener combine to interlocking secure the downspout and the spout together.

Abstract: A method and apparatus for use in destroying a data storage device and separating materials for recycling. The apparatus employs: a first stage of rough cutting wherein the data storage device is shredded into pieces approximately 30 mm×30 mm; a second stage that separates shredded metal material, such as spindles, from non-metal material by use of a magnetized roller having a scraper to the metal material to a first bin and non-metal material to a third stage having an upper level shredder and a lower level shredder for grinding the non-metal material into particle sizes of 10 mm×10 mm or less.

Abstract: A product distribution device shown as an agricultural air seeder in which product distribution can be selective stopped and started in sections of the machine width. The functioning of the section control system is monitored by sensors that directly detect the control member position as opposed to sensing the commanded position of the control member. Likewise, in generating a map of the area covered, the actual detected position of the control member is used instead of the commanded position of the control member. An operator is notified of inconsistencies between the commended position of the control member and the sensed position.

Abstract: An exemplary self-locking actuator mechanism includes a floating plate and a linear actuator. The floating plate defines a first slot that includes a first central portion, a first jog extending laterally from a first end of the first central portion, and a second jog extending laterally from a second end of the first central portion. The linear actuator includes a shaft pivotably connected to the floating plate, and is operable to drive the shaft between a first shaft position and a second shaft position to thereby move the self-locking actuator mechanism between a first locking state and a second locking state.

Abstract: A metering system includes a plurality of metering elements that are independently controllable. A calibration method of the present disclosure includes generating calibration factors for the individual metering elements. Also, a method of the present disclosure includes operating the metering elements according to the respective calibration factor.

Abstract: A security bin formed from a commercially available rectangular plastic bin having removable lids that are secured to the bin to prevent unauthorized access to the items placed therein. The lids are locked with a tamperproof flap and latching hook to prevent access to the bin contents. Plexiglass windows allow viewing of materials placed within the bin. Spring pins allow ease of lid movement for access to the bin contents, or allow removal of the windows to allow stacking for storage and shipping. An optional scanner can be mounted to one of the lids for recording and tracking of storage media placed within the bin.
