Abstract: A method for data interchange includes summing up data associated with an electronic document to provide summed up data, representing the summed up data as one or more bar codes, and returning the one or more bar codes for display and data capture via a bar code scan from either a video display or a printed version of the one or more bar codes. The electronic document may be of any number of formats. The summing up may include taking data from multiple information fields to create the summed up data. The data may include data tags or a step of adding data tags to the data to assist in data interchange may be performed.

Abstract: Preparing data for transmission includes determining bit loading per frequency bin based on channel estimation data to create a data symbol, performing a Fast Fourier Transform (FFT) on the interleaved data symbol array, mapping FFT data output sub-channel to a frequency bin to provide frequency mapped data, and performing an Inverse Fast Fourier Transform (IFFT) on the frequency mapped data to provide IFFT frequency mapped data suitable for transmission using one-dimensional amplitude modulated ultra wideband impulses representing the IFFT frequency mapped data. To recover the data a reverse process is used.

Abstract: A digital lock-in amplifier has a digital-to-analog converter connected between a central processing unit and a source of a signal to be detected or measured and which modulates the signal, an analog-to-digital converter connected between the source of the signal to be measured and the central processing unit, which includes a low pass filtered amplifier, a voltage controlled oscillator having a voltage offset reference supply and a counter, so that the modulated signal is converted to a series of electronic pulses counted over a set period, and a central processing unit which reads, resets and restarts the counter, analyzes the counts received, outputs digital information relating to the amplitude and phase of the signal to be measured or detected, reads a function table and outputs a signal to the digital-to-analog converter. A method detects and measure timed periodic signals using the above digital lock-in amplifier.

Abstract: A hydraulic-elastomeric mount is disclosed having a hydraulic damping decoupler with a flexible membrane mounted for reciprocal movement in a reciprocal partition in response to alternating pressure buildup in two orifice connected chambers separated by the partition and decoupler so as to effect cyclic volume change in the chambers by limited travel of both the partition and decoupler and flexing of the membrane without forcing liquid through the orifice and thus without hydraulic damping thereby.

Abstract: A hydraulic mount assembly includes a pair of mounting members and a first resilient body member and a second resilient body member connected thereto, each body member preferably being substantially bell shaped and forming a cavity. The two body members are connected with the cavities facing each other and separated by an orifice plate to form a closed chamber. A decoupler is mounted in the plate to provide the desired damping action. The body members are preferably molded of elastomeric material, such as rubber, with the first wall portion of the first body exhibiting relatively high stiffness, a second wall portion exhibiting relatively low stiffness and the second body including a third wall portion exhibiting relatively intermediate stiffness. Preferably, the ratio of the three stiffness ratings is 2:0.25:1. In operation, under dynamic loading, the stiff portion of the first body does not allow any dimension change in the longitudinal direction.

Abstract: A bundle carrier attachment for a fork lift truck has a longitudinally extending, rectangular horizontal upper framework which is supported on longitudinally extending parallel tines of the fork lift truck. A pair of vertical support legs extend downwardly, one from each end of one longitudinal edge of the horizontal framework, and a bundle carrier tine is rotatably mounted with respect to each of these vertical load support legs in vertically spaced relation generally below one of the fork lift truck tines. These bundle carrier tines are integral with rotatable bundle tine support shafts which extend up inside of vertical support legs to and through the upper horizontal framework of the attachment.
