Title: Josephus A E P Van Engelen: Innovator in Serial Data Interface Systems

Introduction

Josephus A E P Van Engelen is a notable inventor based in Aliso Viejo, CA (US). He holds a total of 7 patents that showcase his contributions to technology, particularly in the field of serial data interfaces.

Latest Patents

One of his latest patents is a "Serial data interface system and method using a selectively accessed tone pattern generator." This invention performs speed and connection handshaking between Beta signal ports and/or Bilingual ports in a serial data interface system. The system utilizes a tone pattern generator to create a tone pattern signal that operates between approximately 49 MHz to approximately 62 MHz. Additionally, a selecting system is employed to transmit either the tone pattern signal or a data input signal, which includes a driver control signal. A serializer is responsible for serializing either of these signals, while a clock device drives both the tone pattern generator and the serializer. The driver then differentially transmits the serialized signal along a twisted-wire pair.

Another significant patent is the "Precharged power-down biasing circuit." This circuit features a current source connected to the drain of a first NMOS transistor through a first switch. The gate of the first NMOS transistor is linked to the current source, and its source is grounded. A first pre-chargeable capacitor is connected between the gate of the first NMOS transistor and ground. The circuit also includes a plurality of NMOS transistors that form a current multiplier, along with current mirrors connected to the drains of these transistors.
