Abstract: According to some embodiments, a system and method for dispensing a floor coating in a specified ratio of multiple components is disclosed. The system and method may set and maintain a desired ratio of the multiple components by controlling, with a controller, a drive rate of respective pumps configured for propelling the components from a reservoir to a mixer or a dispenser. The controller may be responsive to at least one of a measured actual drive rate, an environmental condition, an actual usage of each component, and an operational parameter of the system, for adjusting a drive rate of the respective pumps to compensate for discrepancies that may affect the ratio of the multiple components.

Abstract: Systems, methods and devices for harvesting plants include an ultrasonic blade for severing top portion(s) of one or more plants. The system includes a first conveyor surface which moves the one or more plants in a linear direction. The ultrasonic blade is disposed above the first conveyor surface at an end of a second conveyor surface of a retrieval system. A first top portion of the one or more plants is severed by contacting a first plant at a first height with the ultrasonic blade. Also, the height of the ultrasonic blade can be adjusted such that a second top portion of the one or more plants is severed by contacting a second plant at a second height with the ultrasonic blade. Furthermore, the ultrasonic blade can have an edge which vibrates at a frequency of 20 kHz or greater to severe the top portion(s).

Abstract: Disclosed herein is a method of assembling an array of light emitting diode (LED) dies on a substrate comprising: positioning dies in fluid; exposing the dies to a magnetic force to attract the dies onto magnets that are arranged at pre-determined locations either on or near the substrate; and forming permanent connections between the dies and the substrate thereby constituting an array of LED dies on a substrate.

Abstract: The Trash Bag Separator, as the name implies is an apparatus to aid in the initial opening of plastic bags such as grocery bags and trash bags. The Trash Bag Separator resembles a plastic credit card folded in half, with adhesive edge paper on each of the inner sides, with the sticky strip on the outer edge. To use the invention, the user places the “book” over the open end of the bag and closes it. The spring nature of the binding causes the “book” to open when released. The sticky paper then separates the two halves of the bag allowing it to be open with ease. The bag can then be removed from the Trash Bag Separator, and the invention is ready to reuse on the next bag.

Abstract: In one embodiment, a timer is disclosed having at least one switch, an alarm, a display device, and a controller. The controller starts a countdown sequence in response to activation of a switch, the countdown sequence having at least one time interval. The controller then activates an alarm at an end of the countdown sequence and at each of the at least one time interval. As well, the controller displays a number of substantially completed countdown sequences on the display device in response to activation of a switch. Other embodiments are discussed, and each can be used alone or in combination with one another.

Abstract: A method and system for a communication system with a communication center, a communication site, a user station and a remote unit allowing the communication center to communicate with the user station over a user channel and communicate with the remote unit over a system channel such that the communication center can monitor, operate or control the remote unit on as needed basis.

Abstract: Noise reducing circuits for electronic receiving instruments, such as telephone receivers in headsets or handsets that are used in noisy locations, provide compensation of the set's receiver unit-to-error microphone transfer function to enhance the noise reduction. Further circuits provide pre-conditioning of the incoming voice signal to make the noise cancellation more effective. The tendency of these noise cancelling circuits to oscillate is substantially lessened by added circuitry which rapidly detects onset of oscillation and momentarily reduces the noise cancellation without interrupting the incoming speech path altogether.

Abstract: A radio or telephone handset configured with the usual transmitter and receiver ends and connecting handle is designed to have physical characteristics well adapted in its acoustic characteristics to complement noise cancellation circuitry. The receiver speaker is mounted in the receiver cap, and the cap is built with a domed, apertured earpiece extending from the exterior surface of said receiver cap. The dome fits into a user's outer ear, thereby to aid in positioning said handset on a user's ear. Openings radially placed on said receiver cap exterior surface and surrounding said earpiece, define an acoustic grill through which signal from said receiver speaker is passed substantially directly to said user's ear canal. Noise absorbing material is placed at strategic locations within the handset interior.

Abstract: The spread spectrum communication system terminal comprises a first subsystem including a first arrangement to encode a locally generally digital data with an error correcting code, a second arrangement for spectrum spreading of the encoded locally generated digital data in at least one mode of operation of the communication system terminal, a third arrangement to receive remotely generated error correcting code encoded digitla data spectrum spread in the one mode of operation and a fourth arrangement to recover the remotely generated digital data. In addition, a second subsystem includes a fifth arrangement frequency hopping the encoded locally generated digital data prior to transmission to a remote location and a sixth arrangement frequency dehopping the encoded remotely generated digital data received from the remote location.
