Abstract: An automatic dry material dispenser for dispensing dry material such as fertilizer to pots or other containers passing by on a conveyor. The device is controlled by a photo-detector or mechanical switch to dispense material when the container is in the proper position. The device consists of a material reservoir, a flexible feed hose, a pipe and elbow which can be pivoted by an electric solenoid and electronics for control. As the pipe and elbow are pivoted to a stop by the solenoid material is expelled from the elbow and down into the passing pot. The amount of material dispensed is controlled by an insert-able cylinder and by selecting the number of dispensing cycles per pot.

Abstract: A power distribution control system for high speed electronics limits peak transient current when entering or exiting circuitry into or out of a system wide freeze mode. The power distribution control system includes power supply circuitry which provides a first supply voltage on a first output line. Multiple circuitry sections are each coupled to and powered by the power supply circuitry. While in the system wide freeze mode, each of the multiple circuitry sections is held inactive by a corresponding one of multiple control signals. A freeze controller is coupled to each of the circuitry sections, and provides the corresponding control signal to each circuitry section. The control signal provided to each particular circuitry section causes the particular circuitry section to enter or exit the system wide freeze mode independently of others of the multiple circuitry sections.

Abstract: A listening conditioning system includes an audio conditioning unit and optionally one or more audio delivery components. A receiver provides at least one receiver channel which receives signals indicative of sound from a source of desired sound, and provides as an output digital sound data for each receiver channel. Digital signal processing circuitry coupled to the at least one receiver channel filters the digital sound data from each receiver channel using a filter profile to obtain filtered digital sound data. A profile upload input is configured to receive a multiple filter profiles, wherein each of the filter profiles corresponds to user preferences or to an audiogram of a user of the listening conditioning system and to a particular sound environment. A profile selection user input can be used to select the filter profile from the multiple filter profiles. A transmitter coupled to the digital signal processing circuitry is configured to transmit filtered sound data from each receiver channel.

Abstract: A method of the invention, embodied for example as computer executable instructions stored on a computer readable medium and executed on a personal computer, includes obtaining a first filter profile for an audio conditioning unit of a sound conditioning system. The first filter profile corresponds to an audiogram of a user of the system. Sound data corresponding to audio to be played is obtained and filtered using the first filter profile. The filtered sound data is played for the user of the sound conditioning system. The user can adjust the first filter profile for current hearing capabilities and specific sound environments without the aid of an audiologist. Multiple filter profiles can be uploaded from the personal computer to an audio conditioning unit of a listening conditioning system.
