摘要:
An openable plant pot assembly for replacing soil in a plant pot without disturbing a plant growing in the plant pot includes a plant pot vertically divided into a first half that is hingedly coupled to a second half. In this way the plant pot is positionable in an open position for replacing soil in the plant pot without disturbing roots of a plant that is growing in the plant pot. A pair of closures is each of the closures is coupled to the plant pot. A pair of engagements is each coupled to the plant pot. Each of the closures releasably engages a respective one of the engagements for retaining the plant pot in the closed position.

A voltage controlled oscillator comprising a substrate and a bilayer graphene transistor formed on the substrate. The transistor has two signal terminals and a gate terminal positioned in between the signal terminals. A voltage controlled PZT or MEMS capacitor is also formed on the substrate. The capacitor is electrically connected to the transistor gate terminal. At least one component is connected to the transistor and capacitor to form a resonant circuit.

A surge suppression system provides surge protection both locally within the radio station building were the power plant and telecommunication equipment are located and remotely next to the radios and antennas located outside of the building on the communication tower. An aerodynamically shaped remote surge suppression unit provides a waterproof enclosure for both surge suppression devices and fiber optic connectors. The unit has reduced wind load and reduced weight and can be placed on a wide variety of different radio tower and building structures with tight space restrictions. A rack mountable surge suppression unit provides local in-line surge suppression protection for the electrical equipment located in the communication station. A unique surge suppression tray is hot swappable so that multiple surge suppression devices can be replaced at the same time without disrupting radio operation.

The present invention concerns a process for preparing a polymer comprising at least one gel polymerization step (E) in which the following are contacted: ethylenically unsaturated water-soluble monomers, the same or different; a source of free radicals adapted to the polymerization of the said monomers, typically a redox system; and a radical polymerization control agent, preferably comprising a thiocarbonylthio —S(C═S)— group; with a concentration of monomers in the reaction medium of step (E) sufficiently high to cause gelling of the medium if polymerization was conducted without the control agent.

An instruction-based parallel median filtering processor and method sorts in parallel each combination of pairs of inputs into greater and lesser values; determines from that sorting the minimum, maximum and median filter values of the inputs; processes one of those values and provides the processed value as an input; and applies an instruction for providing one of the values to the processing step, and at least one other instruction for enabling indication of at least one of the maximum, minimum, median filter values.

A programmable compute unit with an internal register with a bit FIFO for executing Viterbi code is configured to accumulate in the forward path the best-path to each state in an internal register and store the survivor trace back information bit for each state in each stage in a bit FIFO; and in the trace back, selecting the optimal best-path through the Viterbi trellis by tracing through the bit trace back information survivor bits beginning with the survivor bit of the last stage path; and generating in response to the Viterbi constrain length and a current bit FIFO address, the next bit FIFO address and decoded output bit for the next previous stage.
摘要:
A method of detecting periodic activity patterns associated with the viewing of audio video content is described. The method includes: recording activity data in an activity log; suppressing the activity log one or more times to suppress non-relevant activity data thereby producing one or more sets of suppressed activity data; passing the one or more sets of suppressed activity data through a signal processing function to convert the one or more sets of suppressed activity data to one or more frequency responses; and analysing the one or more frequency responses to detect the periodic activity patterns. Related apparatus and methods are also described.
