Abstract: Low-pH compositions are provided for dissolvable solid unit dose formulations that can be used with a wand apparatus to clean a toilet surface. The formulations include surfactants, an organic acid and an organic acid buffering agent, and virgin soap pellets and/or a cellulose filler. Formulations having antibacterial efficacy include an anionic surfactant present at about 15% to about 30% by weight of the composition, an organic acid-buffer system in an amount sufficient to provide toilet water with a pH which is less than 4.6 when the composition is dissolved in toilet water, and virgin soap pellets.

Abstract: A dissolvable toilet cleaning solid tablet includes an anionic surfactant; virgin soap pellets; and borax, and desirably, a carbonate or bicarbonate salt; and an acid. The borax comprises about 0.5% to about 10% by weight of the composition, and the virgin soap pellets comprise about 12% to about 25% by weight of the composition.

Abstract: A compressed unit dose toilet cleaning tablet for use with a wand. The unit dose contains surfactant, organic acid, and an organic acid buffering agent and is compressed into a tablet or puck that dissolves in toilet water after cleaning. The tablet has a top surface, a bottom surface, a height extending from the top surface to the bottom surface, and a diameter. The top surface has an indentation adapted to receive and engage with a wand. A ratio of the height to the diameter of the tablet is between 0.2 and 0.3. A kit contains a plurality of the tablets and a wand.

Abstract: A cleaning system includes a handling tool for a dissolvable cleaner block. The handling tool includes a wand and a retainer arrangement attached to the wand and moveable between a retaining position and a releasing position. The retainer arrangement is configured for removably attaching the wand to the dissolvable cleaner block when in the retaining position. The retainer arrangement is configured for releasing the dissolvable cleaner block when in the releasing position. The retainer arrangement includes at least one selectively moveable engagement member that removably engages the dissolvable cleaner block in the retaining position.

Abstract: A wireless audio system using low overhead in-band control and audio transmission is provided. The wireless audio system includes a first wireless audio device configured to operate separate physical layer channels for audio data and control data, and transmit the audio data and control data using a single wideband carrier. The wireless audio system also includes one or more second wireless audio devices configured to receive the audio data and control data, and execute an instruction based on the control data.

Abstract: A method for synchronizing baseband clocks in an OFDMA wireless microphone system is disclosed. An example method includes receiving a plurality of pilot subcarriers from an audio transmitter. The method also includes determining a timing offset estimate based on the pilot subcarriers. The method further includes determining a tuning value by passing the timing offset estimate through a proportional-integral controller. The method still further includes determining a modified reference signal by modifying a reference oscillator based on the tuning value. And the method yet further includes controlling (i) an audio sample clock and (ii) an antenna data clock based on the modified reference signal.

Abstract: A snow removal system. The snow removal system includes a housing having an inlet disposed on a front side thereof, wherein the inlet is in fluid communication with a first chamber. An auger is disposed transversely across the first chamber, wherein the auger is operably connected to a motor within the housing. The auger rotates about a longitudinal axis thereof to mash snow and transport the mashed snow into a second chamber when the motor is actuated. The second chamber includes a primary heating element therein, the heating element designed to heat snow within the second chamber to produce steam. An outlet is disposed through a sidewall of the second chamber, wherein the outlet can emit steam from the second chamber.

Abstract: A wireless microphone system is disclosed. The system includes a plurality of wireless microphones each classified in accordance with one or more audio quality parameters. The system also includes a control device communicatively coupled to the plurality of wireless microphones. The control device is configured to determine that a first wireless microphone corresponds to a first audio classification, and that a second wireless microphone corresponds to a second, different, audio classification. The control device is also configured to determine a first modulation and coding scheme for the first wireless microphone based on the first audio classification, and a second modulation and coding scheme for the second wireless microphone based on the second audio classification. The control device is further configured to transmit, to the first and second wireless microphones respectively, the determined first and second modulation and coding schemes.
