Appl. No.:

12/011204

Inventors:

Kenneth C. Dyer - Davis CA, US
Harvey Scull - Naperville IL, US

Assignee:

Vintomie Networks B.V., LLC - Dover DE

International Classification:

H04B 3/28

US Classification:

333 12, 333 171

Abstract:

An adaptive electromagnetic interference (EMI) detection and reduction device for multi-port applications is provided. The invention includes at least two physical devices (PHY), where the PHYs transmit data along wire pairs to a register jack (RJ). The transmissions create EMI along the wire pairs, where the transmissions have constructively interfering resonant frequencies having phases and amplitudes. An antenna is disposed proximal to each RJ, where the antennae detect each frequency. A resonating network determines a peak amplitude of each frequency, an envelope detector amplifies each peak amplitude from the resonating network. A discretization circuit converts the amplified peak to discrete amplitude values, where the discretization circuit transmits the discrete amplitude values to a controller. The controller receives the discrete amplitude values from the discretization circuit, and communicates with each PHY, where a phase or frequency of the PHY signal is modified to minimize the constructive interference between the resonant frequencies.

International Classification:

G11B 502

US Classification:

360 26

Abstract:

A test set is disclosed for measuring read/write head skew in a magnetic tape recording system. Read head skew is measured by reading a reference tape having substantially identical alternating signals recorded in all tracks thereof and measuring the time between the receipt of signal peaks of corresponding portions of the signals read from any two tracks of the reference tape. Pulses from a high frequency oscillator are counted during the time between the signal peaks to obtain counts which are representative of the read head skew. These counts are averaged over a number of cycles of the alternating signals and displayed on a digital display. Write head skew is measured by writing an alternating signal onto two tracks of a magnetic tape and reading the two tracks with a properly aligned read head. Maximum head skew is determined and displayed by comparing the contents of a display register to the present count and transferring the present count into the display register if the present count is greater or equal to the contents of the display register.

Abstract:

A shuttlecock loading mechanism with a grabbing mechanism and a pair of ejecting wheels defining a wheel plane. The grabbing mechanism receives a shuttlecock entering the loading mechanism in a vertical position and ejects the shuttlecock from the loading mechanism in an orientation parallel to the wheel plane wherein the pitch of the wheel plane about a wheel horizontal axis is selectively indexed about the wheel's horizontal axis.
