Latest Patents

One of Zalph's latest patents is focused on network connected device protection. This invention outlines a method and apparatus for alerting an operator when a terminal device is disconnected from the network. The network controller adapter connects to a network control computer, which periodically halts normal data communication to scan network ports. This scanning process ascertains the present and absent status of terminal devices at each port. The status is detected by passing a current through a port and measuring the feedback voltage. If a status change occurs between scans, the operator is alerted through various means, such as sounding an alarm or transmitting a message over the network.

Another significant patent by Zalph involves calibration apparatus for brightness controls of digitally operated displays. This invention pertains to a TFT LCD display with a PEL matrix, where different drain lines of the TFTs receive varying drain voltages to achieve a preset number of gray scales. The calibration process is conducted during factory settings using a test PEL that closely resembles the user-viewable PELs. The calibration is accomplished by measuring output voltages of a photodiode and constructing a unique transmissivity versus drain voltage for the display.
