20100125942 | Pool Skimmer with Integral Disinfectant Dispenser - A swimming pool skimmer formed to include an integral disinfectant dispenser. The disinfectant dispenser is adapted to enable infinite adjustment to the level of disinfectant dispensed into the normal flow of the pool water. The skimmer includes a valve that is used to adjust the flow of water distributed to the disinfectant dispenser. The flow rate of water entering the dispensing chamber is controlled by the valve, which controls the water level within the dispensing chamber. The amount of water exiting the dispensing chamber is controlled by a vertically extending elongated flow slit. The higher the water level in the dispensing chamber causes more exposure to the chlorine tablets, increasing the chlorine level in the dispensing water. Chlorinated water exits the flow slit and enters the skimmer main chamber. | 05-27-2010 |
20100126085 | Swimming Pool Brace Assembly - A swimming pool brace assembly having a brace and bracket used to attach a concrete form. The bracket positions the concrete form between the concrete footing and the deck of the swimming pool. The swimming pool brace is provided with receptacles that are adapted to receive the brackets, which are used to retain the position of the concrete form. The receptacles of the brace allow the brackets to be attached to either side of the brace. The bracket includes a retention feature that is configured to retain the bracket in position once inserted into the receptacle of the brace. The bracket includes a series of radially spaced inwardly extending protrusions that engage the concrete form. The protrusions are adapted to deflect to adjust for variations in the size of the forms. | 05-27-2010 |
20120110728 | Swimming Pool Skimmer Cover - A skimmer cover assembly includes a cover that is adapted to fit over the face flange of the skimmer or pool wall to prevent water from entering the skimmer assembly. The cover is secured to the skimmer by use of a draw bolt that is threaded at one end and includes a thumb screw or wing nut at a second end. The threaded end is adapted to be threaded into a support brace that is braced against an inside surface of the skimmer housing or to the skimmer housing itself. Tightening the draw bolt with the thumb screw draws the cover tightly against the face flange of the skimmer. The cover includes a gasket seal about its perimeter to form a watertight seal with the face flange of the skimmer. The draw bolt also has an o-ring that is positioned between the thumb screw and the cover to prevent water from leaking past the cover. | 05-10-2012 |
20140260004 | POOL LINER RETAINER - A pool stair assembly includes step members having riser panels and tread panels, the step members joined together to form a multi-step structure. In illustrative embodiments, a spacer is located between a connection flange of a first step member and a riser panel of a second step member to form a channel therebetween, with one or more detents extending into the channel. A swimming pool liner includes locking tabs at predetermined locations that correspond to the channel, the locking tabs insertable into the channel to secure the liner to the step members. When the locking tab is inserted, a lip of the locking tab is compressed against the detent to move the locking tab past the detent when sufficient downward force is applied. The lip naturally biases back to its original position after passing the detent, preventing removal of the locking tab from the channel. | 09-18-2014 |

20100202262 | BLOCK NOISE DETECTION AND FILTERING - Systems and methods for block noise detection and filtering are disclosed. One embodiment includes, computing difference magnitudes in pixel values for adjacent pixels in the image. The difference magnitudes can include horizontal difference magnitudes for horizontally adjacent pixels and vertical difference magnitudes for vertically adjacent pixels. One embodiment further includes using normalized sums of the difference magnitudes to determine a set of noise characteristics of the block noise and a set of image characteristics of the image and configuring inputs to the block noise filter using the set of noise and image characteristics. | 08-12-2010 |
20130162901 | RINGING SUPPRESSION IN VIDEO SCALERS - Embodiments are generally directed to ringing suppression in video scalers. An embodiment of a method includes receiving a stream of video data, received video data including sets of video data values, and storing a first set of video data values in a memory. A first set of scaled values for the set of video data values is determined based on a scaling technology, and a second set based on linear interpolation. The method includes detecting rate of change in amplitude for received video data, generating a mixing control signal based at least in part on the rate of change, mixing first set of scaled values and second set of scaled values based at least in part on mixing control signal to generate blended set of coefficients, and generating scaled video data output using the set of blended values. | 06-27-2013 |

20140340579 | Encoding Guard Band Data For Transmission Via A Communications Interface Utilizing Transition-Minimized Differential Signaling (Tmds) Coding - The present disclosure is related to a hardware component for communications over a multimedia communication interface. In one embodiment, a hardware component includes a disparity circuit that stores a disparity value. The disparity value indicates the disparity between the number of “1”s and the number of “0”s previously transmitted by the hardware component. The hardware component also includes circuitry for receiving multimedia data to be scrambled, encoded and transmitted by the hardware component. In one embodiment, the multimedia data includes video data and data island data. In one embodiment, the hardware component generates transition minimized intermediate codes based on values in the guard band data included within the video data and data island data. The hardware component generates encoded guard band codes that are transition minimized as well as direct current balanced. The hardware component transmits the encoded guard band codes over a differential pair of the multimedia communication device. | 11-20-2014 |
