Latest Patents

One of Hoffman's latest patents is a playing card coding system and apparatus for dealing coded cards. This innovative system marks playing cards with binary codes adjacent to both side edges of the face of each card in a standard deck. The code includes a precode that signals a card reader to read the code in the proper bit sequence, depending on the direction of card movement past the reader. The binary code consists of six bits to represent the face value and suit of the card, along with a four-bit error detection code capable of detecting errors of two bits in the code. The coded cards can be dealt either manually or automatically according to at least one predetermined program. The cards are passed over photocells that read the binary codes on the face of the card, with outputs sent to a microprocessor that compares the code to the predetermined program and directs the card to the appropriate player location.

Another significant patent is for an improved floppy disc drive featuring direct disc rotational drive. This design is characterized by a step motor with multiple pole pairs, with pole pieces fabricated from a portion of the drive housing at predetermined locations. The disc has radial webs positioned to align one pair at a time with successively energized pole pairs, resulting in a highly efficient and compact disc drive motor. The assembly also includes a read head drive with a step motor and transmission means for driving the read head radially concerning the floppy disc. Additionally, mechanisms are provided to engage the disc with the drive only when the disc is properly seated within the assembly.
