摘要： We disclose a method of tagging pharmaceutical and nutritional products with nanoparticles which include noble metals. The disclosure describes a plurality of nanoparticles each with either a different size and/or shape. The nanoparticles of different sizes and shapes are distinguishable using spectroscopic techniques because each is associated with different optical properties and have a different spectral signature. The different optical properties are at least due to the unique size or shape of the nanoparticles. Each of the plurality of nanoparticles may be associated with a different characteristic of the tagged pharmaceutical or nutritional product. The method includes mixing the nanoparticles with or adhering the nanoparticles to the tagged pharmaceutical or nutritional product. Two or more of the plurality of nanoparticles may be mixed with or adhered to the tagged pharmaceutical or nutritional product in a ratio and the ratio may be associated with a characteristic of the product.

摘要： Methods for negotiating optimum parameters for communicating between a wireless control device and a wireless user device are disclosed. The methods generally include transmitting a frequency-hopped and spread negotiation signal using network-maximum parameters. The initial parameters make the negotiation signal long-range but low-data. The methods further include adjusting the initial parameters to optimal parameters based on a link budget and data rate requirements received in response to the negotiation signal. The signals are communicated on the 902-928 MHz unlicensed ISM band, and the parameters include spreading factor, output power, and carrier frequency channel bandwidth.

摘要： A method of powering an intermittent-duty cycle winch is disclosed. The method includes identifying a number of amp-hours required to power the winch through one duty cycle, identifying a minimum required rest period between two consecutive duty cycles, and assembling a power supply unit that powers the winch based, at least in part, on the duty cycle and the rest period. The duty cycle is mechanically or thermally limited. The power supply unit includes at least two components: a power storage unit and a charging unit that recharges the power storage unit during the rest periods. The power storage unit powers the winch through at least one duty cycle. The charging unit recharges the power storage unit during the rest period so that the power storage can power the winch through at least a second duty cycle that immediately follows the end of the minimum required rest period.

摘要： A winch is described comprising a compressional wiper system activated by a sensor that detects which direction a cable is moving. When the cable is being pulled in, the compressional wiper system tightens a clamp or fastens a rotatable clamping device inside a fairlead. The tightened clamp or fastened clamping device act to decrease the likelihood that dirt, mud, debris, or other materials that adhere to the cable accumulate within the winch, by wiping or scraping off said materials from the cable.

摘要： Embodiments of overhead mounting systems are described herein. Various embodiments may include a channel, one or more covers, and one or more cover spacers. The channel may include a channel base, at least two channel walls, and at least two channel ends. The channel walls may be connected perpendicularly to the channel base such that the channel is u-shaped. The channel walls may each comprise a plurality of channel wall openings. The covers may include a cover base, at least two cover walls, and at least two cover ends. The cover walls may each include one or more inward protrusions. The cover ends may be concaved along the cover base such that a cover base length is less than a cover wall length. The cover ends may be concaved along one or more of the cover walls.

摘要： The present invention is directed to an embedded interconnecting drive system. The drive system is used to deploy and retract flexible, roll-up panels away from or onto a roller drum as the drum rotates on its longitudinal axis. In this invention, a plurality of cogs, each comprising a semi-tubular recess and tapered shaft, interact with each other to induce the flexible panel to move in concert with the roller drum as the roller drum rotates, preventing the flexible panel from unraveling on the drum. The cogs compel the flexible panel to deploy away and downward from the drum as it rotates deployingly, and to retract onto the roller drum as it rotates retractingly. This invention discloses details of the cog and a complimentary annular lock disc used to secure the cog to a flexible panel. Further, this invention discloses a plurality of embodiments of the embedded interconnecting drive system.

摘要： A system and method for a winch fairlead pivot are described for reducing friction between a line and the fairlead when letting out or pulling in a line. The winch fairlead pivot includes an upper and a lower pivot that insert into an upper and a lower cavity in the fairlead-frame and upon which the fairlead-frame pivots. The direction of the pivot is dependent upon the direction of a load connected to the line.

摘要： A photovoltaic modular connector system is disclosed. Electrically conductive contacts embedded into the surface of each of one or more photovoltaic (PV) modules provide the connection point for two PV modules to be connected together.PV modules are connected together by removing a protective backing material from an adhesive area surrounding a first set of contacts of a first PV module, and adhering to an adhesive area surrounding a second set of contacts of a second PV module, the adhesive making the connection and sealing and protecting the contact area.No external wiring, connectors or devices are required to make the electrical connection between two PV modules. Contacts are integral and embedded into the surface of each individual PV module. The PV modules have adhesive on the back to allow them to be adhesively attached to a surface without additional mounting hardware.

摘要： A vehicle winch mechanism includes a drum, a motor and transmission, at least one drum and motor side support, at least one battery, and a motive trickle charge mechanism. The drum pays out and takes in a line. The motor and transmission drive the drum. The side supports couple the drum, the motor, or both to the vehicle. The battery provides power to the motor. The motive trickle charge mechanism charges the battery. In one embodiment, the motive trickle charge mechanism includes a permanent magnet, an enclosure housing the magnet, and two or more sets of conductive coils wrapped around the enclosure and electrically coupled to the battery. The enclosure houses the magnet such that the magnet freely moves and changes orientation within the enclosure. The coils of an individual set of coils are aligned along parallel planes, and the coils of separate sets are aligned along intersecting planes.
