Abstract: A user interface is configured to allow an end user to create an electronic form based on a template by identifying fields in the template to receive inputted data. The end user may also identify conditions specifying actions to be taken based on the data inputted into the fields and calculations to be performed on the data inputted into the fields. A conditional engine processor and a calculation engine processor are configured to create the electronic form based on the template and the identified fields in the template. A second user interface is provided and configured to display the electronic form and receive data input into the fields of the electronic form. Upon receiving data input into a field of the electronic form by an end user, the end user is directed to another field of the electronic form for inputting data, based on the data input into the field by the end user.

Abstract: The present invention is a device for supporting the weight of a gun, in a vertical orientation, with the barrel end of the gun facing the ground. The device comprises a platform large enough to fully engage the barrel end of a rifle or shotgun, and an outer lip fully encompassing the platform to prevent the gun barrel from slipping off the platform edge. In addition, the device has a clip for engaging an ankle strap, which secures the device to the exterior of the wearer's footwear and ankle. With the present invention, a sportsman may safely place the weight of a rifle or shotgun to his or her foot without sacrificing ready access to the weapon.

Abstract: An audio system (100) is provided with improved adaptive filter (206) to automatically adjust signal gain depending on the ambient noise level. The original music signal passes through a normalized adaptive filter (206), and is subtracted from the ambient room signal detected by a microphone (120), resulting in an error signal that is an estimate of the ambient noise. The error signal is used to update a set of adaptation coefficients so that the normalized adaptive filter more accurately simulates the room transfer function, resulting in an better estimate of the ambient noise. The audio system (100) is calibrated automatically upon initial use to determine adaptation coefficients and noise threshold level to prevent runaway gain. System parameters are adjusted using a controller (124) with a user-friendly interface (400).

Abstract: A method for shifting the timbre and/or pitch of an input signal samples the input signal at a first rate and stores the samples in a memory buffer. A digital signal processor resamples the stored input signal at a rate that differs from the first rate at which the input note is originally sampled and stores the resampled input signal in a second memory buffer. A pitch shifter shifts the pitch of the input signal by periodically scaling the resampled input signal by a window function to create an output signal. The rate at which the resampled data is replicated by the window function determines the pitch of the output signal.
