A passive electrical component is described including a substrate, at least a first, second and third electrically conductive pad, each disposed on the substrate and at least a first electrical device fixedly attached to the first pad and the second pad. The first electrical device is electrically connected to the first and second pads. The third pad is devoid of electrical connection to either the first or the second pads. The component is recognizable by both a Computer Aided Design program and an automated component assembly machine.

A method of operation of a stepper motor, especially as used in connection with a picker assembly employed in a data storage library and a picker assembly that may utilize the stepper motor.

The present invention provides an apparatus and methodology that allows a host computer to control a data storage device that is remotely located relative to the host computer utilizing the same software that is used to control data storage devices that are locally or directly connected to the host computer. In one embodiment, a host computer is provided that includes a virtual adapter that is capable of converting unencoded SCSI command related information from an operating system into encoded SCSI command related information that is capable of being transmitted over a network to a remotely located SCSI data storage device, i.e., a SCSI data storage device that is separated from the host computer by more than the distance set forth in the SCSI specification. The virtual adapter is also capable of decoding encoded SCSI command related information received from a remotely located SCSI data storage device into unencoded SCSI command related information that is suitable for processing by the operating system. The remotely located SCSI storage device includes a controller that is capable of decoding the encoded SCSI command related information that it receives from the network into unencoded SCSI command related information that is suitable for application to a SCSI data storage unit and vice versa.

Network attached tape storage system

Taped data copying is disclosed having the capability of high speed simultaneous generation of multiple data copies. Storage media, for example magnetic tape, having data, normally in digital form, recorded thereon is read at a master unit and electrical signals indicative of the data is generated and broadcast over a computer bus to a plurality of addressable memory units where data-indicative information is simultaneously written into the plurality of memory units. Each memory unit is connected with a different associated one of a plurality of magnetic tape-containing data copying units so that data-indicative information stored in each memory unit is read and reliably copied onto the tape at the associated data copying unit. A processing unit is included to control writing information into the memory units, reading information stored in the memory units, and verifying the integrity and content of data copies.

Taped data copying utilizing multiple addressable memories

A sightless indicating system and method is disclosed that is useful as an indicating device for diverse equipment, including equipment such as an electronic calculator, and is particularly useful by a blind person. When utilized as a part of an electronic calculator, a standard calculator keyboard is modified to include a sign key and an output key so that an operator can initiate output indications and determine the sign of such indications in addition to initiating the customary numerical and function inputs. The customary numerical and function inputs are processed in conventional manner except that the calculator output is converted to a sightless indicating form, such as audible signals indicative of output. For an audible indication of the modified calculator, the output key is depressed and the value of each digit to be indicated is converted to a series of equally spaced output tones at substantially the same frequency with a different number of tones being utilized for each digit to differentiate therebetween. In addition, a steady, low-level output tone is utilized to indicate a decimal point in the audible output of a calculator, while an output tone of the same frequency as that used to indicate digits is utilized to indicate the sign of the output when the sign key on the keyboard is depressed. Manual or automatic sequencing modes can be selected and in the automatic sequencing mode, the output key need be depressed only once for indication of all digits whereas in the manual mode, the output key must be depressed for each digit to be indicated with leading zeros being suppressed in either operational mode.
