Patent CA-2425088-A1 (CA)
Inventor: KERR JOHN K
IPC: H03G3/20
Filed: 2003-03-28
Abstract: A self contained device for automatically controlling the sound level of a TV, audio or audio-visual product without interfering with the functions or features of the existing product. This invention makes newly employed use of linear automatic gain control (AGC) circuit theory, whose function is to automatically amplify or attenuate varying input signals in order to obtain a relatively stable output signal. The automatic level-adjusting device (the subject of this invention) is connected between two audio products. It receives its input signal from conventional phono audio output jacks and sends its output signal to audio input jacks (which is a common built in feature of many, worldwide, consumer and industrial electronic audio-visual products). The received audio signal is applied to this invention's AGC circuit, which has been specifically designed to work within a predetermined range of signal levels and also as having a fixed maximum amplification level. When low input signal levels are received, the invention's AGC' circuit acts to amplify the input level to produce an output that is an amplified linear function of the input. Alternatively, when received high input signal levels reach a preset threshold value, the AGC circuit acts by attenuating the input signal in order to maintain an essentially constant output level. It is by this method of conditioning the audio signal before it is received by the existing product, that effective sound level control is achieved. This is done without direct functional interference with, or incorporation within the product.

Title: Fan-stator interaction tone reduction
Inventor: TSE MAN-CHUN
IPC: F04D29/66
Filed: 2001-11-16
Abstract: A gas turbine engine rotor assembly such as a fan (14) or compressor (16) includes fan blades spaced axially from stator vanes (46) inside an annular duct (55). A controlled air blowing system (54) is secured to the annular duct (55) and adapted to blow a hot air flow (56) in a direction opposite to the rotation of the fan blades into the annular duct (55) between the fan blades (14) and the stator vanes (46), to impart an opposite rotational momentum with respect to the air compressed by the rotor blades, in a asymmetrical pattern to interfere with or destroy a symmetrical pattern of the blade rotation-wake of the compressed air, thereby reducing the strength or preventing the generation of the spinning mode so that the fan-stator interaction tones are significantly reduced.

Abstract: The present invention provides a blast-resistant panel and container to protect objects against the blast force from an explosive device. The invention consists of a first layer whose shape and/or size may be altered by the blast force without substantial release of gases therethrough, a compressible second layer, and a third layer. When absorbing a blast, the first layer moves toward the third layer thereby compressing the second layer, the second layer absorbs the blast energy, and the third layer prevents substantial displacement of the second layer. In the preferred embodiment, the first layer is constructed of overlapping plates which can slide relative to one another. In another embodiment, the first layer is constructed of axially-slidable plates, the movement of such plates being guided by guiding ribs.

Title: Method to modulate plant growth by injecting a plug at lift
Inventor: INGRAM MARK
IPC: A01G29/00
Filed: 2003-09-12
Abstract: A method for modulating plant growth is provided whereby seedlings that are grown in containers such as blocks are fertilized at lift. Prior to fertilization, the block, which has numerous plug cavities, is restrained. The seedlings, which are grown in plugs formed in plug cavities, are supported and a bore is drilled into the bottom of the plug. The bore extends to the top of the plug to produce a small port, which serves as a port for expulsion of air during the injecti on operation. The fertilizer is measured in a metering roller and is then pneumatically injected into the bore in the plug. Upon completion of the injection, the bore is closed to reduce the loss of fertilizer from the plug . The various operations may be automated or performed manually.

Title: Method and apparatus for increasing receiver immunity to interference
Inventor: WEILAND ANA L
IPC: H04B1/7075
Filed: 1995-12-11
Abstract: The process of the present invention adjusts the input gain by a predetermined amount. The receiver processing measures the gain change in the IF signal power.      If the change is less than the predetermined amount, the CDMA signal and jammers are below the noise floor and, therefore, the gain is increased. If the IF signal power change is equal to the predetermined amount, the CDMA signal is above the noise floor and the interference is minimal.      Therefore, in this case, gain adjustment is not necessary, but increasing gain will improve sensitivity. If the IF signal power change is greater than the predetermined amount, the interference is evident and the gain is reduced to reduce the intermodulation products. This process is used until the receiver is operating at the best compromise between interference and noise figure.
