摘要:
A jacketed light emitting diode assembly is provided, which includes a light emitting diode, a lens body containing a semiconductor chip and a set of positive and negative contacts exiting said lens body from a base portion. An electrical wire set of first and second electrical wires are connected to the positive contact and the negative contact, respectively. An integrally molded plastic jacket is provided at the base portion of the lens body around said positive and negative contacts and connection points between the contacts and the wire set to provide a seal at the base portion and at the connection points against moisture and airborne contaminants, whereby a portion of the first and second electrical wires project from the jacket to define bendable contacts for providing an electrical connection with a lamp husk. An optional light transmissive cover may further be provided. A waterproof light string including one or more of the jacketed light emitting diode assemblies is also provided, as are related methods.

An LED light string employs a plurality of LEDs wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage or rectified AC input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. The same method that apply to matching the sum of the LED lamps (VAC values) to the AC input, or applied voltage in an AC circuit apply to matching the sum of the LED lamps (VP values) to the full-wave or half-wave rectified AC (VP) voltage applied. Filtering capacitors may also be employed.

Field Effect Transistors (FETs) are used to regulate current in a light emitting diode (LED). FETs are fundamentally voltage driven devices, where output current is governed by junction voltage. Since junction voltage can be controlled with little or no support circuitry, FETs present a solution to current regulation where cost, complexity, and perhaps even size are important.

A computerized method and system for managing a media advertising proposal from inception to completion of an order with one or more media outlets are described. An embodiment of the method includes receiving a customer request for placement of advertising in one or more media outlets, creating a media advertising proposal, that includes schedule of advertising for the requested placement, based on user inputs into a media proposal tool, storing the media advertising proposal in a database connected to the media proposal tool, accessing one or more external applications to integrate information and data into the media advertising proposal, assigning a grade to the media advertising proposal, entering the media advertising proposal into a computerized workflow in the media proposal tool for review and approval, and if the media advertising proposal is approved, injecting the media advertising proposal as an order into a traffic and billing system.
摘要:
Advertisements can be paired based on their context to achieve increased advertising effectiveness that might not be able to be achieved without the pairing. The advertisements can be paired based on a user's preferred context, which includes an attribute of one of the advertisements. For example, a conditional advertisement can be paired with a scheduled advertisement based on an industry type, the length of the other advertisement, or some other characteristic. Each characteristic can be given a weight, to aid in pairing determinations. The effectiveness of the pairing can be tracked, and the context can be iteratively modified based on the measured effectiveness of the advertising campaign. Pairing can be performed without identifying other advertisers, even though weighting factors may take a sponsor's identity into account. Pairing can be constrained by a master schedule and by a maximum allowed number of conditional spots.

An LED light string employs a plurality of LEDs wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. The LED light string interfaces to the source voltage using a common household plug; it may also include a corresponding common, household socket, coupled in electrical parallel, to enable multiple light strings to be connected to each other from end to end. In order to directly drive a network of diodes without current-limiting circuitry, the voltage of each series block of diodes must be matched to the input source voltage. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. For the voltage to be “matched,” in each series block, the peak input voltage must be less than or equal to the sum of the maximum diode voltages for each series block.
