Patent number: 6189592Abstract: A roll-up shade is doubled and its ends suspended from a head rail that is mounted above a window. One end is attached to a roller tube and the other end is attached to a stationary tube, with a bight being formed between the tubes. A first sheet is defined from the bight to the roller tube and a second sheet is defined from the bight to the stationary tube. A weighty rod is positioned in the bight to cause the bight to sag away from the head rail, and a shade guide surrounds the rod to guide the shade. With this structure, the roller tube can be rotated to pull up the first sheet and raise the bight or to lower the first sheet with bight, with the second sheet (i.e., the sheet that is directly attached to the stationary tube) remaining unmoving above the bight. The shade is patterned such that when the shade is raised and lowered, the relative motion between the two sheets causes the shade to alternatingly assume high and low opacity configurations. The roller tube can be motorized if desired.Type: GrantFiled: October 18, 1999Date of Patent: February 20, 2001Assignee: Harmonic Design, Inc.Inventor: Douglas R. Domel

Patent number: 6062290Abstract: An automatic control apparatus for window coverings where the control apparatus is mounted in the space between a headrail and a window. The control apparatus is mounted to the rear surface of the headrail so as to overlie the rear surface of the headrail and is blocked from view by the headrail. A battery pack may be mounted to the control apparatus along the rear surface of the headrail and would also be blocked from view by the headrail.Type: GrantFiled: February 27, 1998Date of Patent: May 16, 2000Assignee: Harmonic Design, Inc.Inventor: Douglas R.

Patent number: 6060852Abstract: A mini-blind actuator has a motor and a housing that holds the motor and a dc battery. The rotor of the motor is coupled to the baton of the mini-blind for rotating the baton and thereby opening or closing the slats of the mini-blind. Alternatively, the rotor is coupled to the tilt rod of the blind to rotate the tilt rod and thereby open or close the slats of the mini-blind. A control signal generator generates a control signal for completing the electrical circuit between the battery and the motor. The control signal can be generated in response to a predetermined amount of daylight or in response to a user-generated remote command signal. The actuator can be used to rotate the slats of horizontal or vertical blinds, or the sections of a pleated shade. Or, the actuator can be used to rotate the hollow rotatable tube of a roll-up shade.Type: GrantFiled: September 4, 1997Date of Patent: May 9, 2000Assignee: Harmonic Design, Inc.Inventors: Douglas R. Domel, Winston G. Walker

A control signal generator generates a control signal for completing the electrical circuit between the battery and the motor in which reference to an element in the singular is not intended to mean "one and only one" unless explicitly so stated in the claim, but rather "one or more". The control signal can be generated in response to a predetermined amount of daylight or in response to a user-generated remote command signal. The actuator can be used to rotate the slats of horizontal or vertical blinds, or the sections of a pleated shade. Or, the actuator can be used to rotate the hollow rotatable tube of a roll-up shade.Type: GrantFiled: January 28, 1998Date of Patent: March 16, 1999Assignee: Harmonic Desing, Inc.Inventors: Douglas R.

Patent number: 5725040Abstract: A suspension cord guide for a window blind includes an L-shaped guide member positioned within the head rail of the blind. The guide member is positioned adjacent an opening in the head rail through which the suspension cord extends. Also, the suspension cord guide includes a hollow spindle surroundingly engaged with a tilt rod in the head rail, and the spindle is formed with an abutment surface on its end nearest the opening. A finger of the L-shaped member extends toward the spindle, with the suspension cord being fed onto the spindle next to the abutment surface by the guide member. In addition to guiding the cord onto the spindle, the finger of the L-shaped guide member contacts the coil of the suspension cord that is established on the spindle nearest the finger.Type: GrantFiled: June 20, 1996Date of Patent: March 10, 1998Assignee: Harmonic Design, Inc.Inventor: Douglas R.

Patent number: 5319519Abstract: An apparatus for holding a portable hard disk drive in a desk-top personal computer (PC) has a housing that fits into the 3.5" form-factor cavity which is formed in most IBM.RTM.-compatible PCs. The portable hard disk drive is disposed in a protective sleeve, and the sleeve with disk drive can be manually advanced into the housing to electrically engage the PC with the portable hard disk drive. An ejector mechanism is provided in the housing for manually ejecting the disk drive from the PC upon completion of data transfer between the disk drive and PC. The ejector mechanism includes a latch mechanism movable from a latched configuration, wherein the disk drive is held in electrical contact with the PC, and an unlatched configuration, wherein the disk drive can be ejected from the housing.Type: GrantFiled: November 20, 1992Date of Patent: June 7, 1994Assignee: Summatec Computer CorporationInventors: Dan C.

Patent number: 5157565Abstract: A cassette loader for a DAT cassette drive includes a specially-constructed, multi-chamber magazine which rides in an elevator to bring selected ones of a plurality of cassettes in the magazine into operative alignment with the inlet of the DAT cassette drive. A push-pull mechanism is positioned at a distance from the DAT cassette drive inlet so that the magazine is transported between the mechanism and the inlet. The mechanism includes a motor-driven scissors mechanism whose output arm extends into a selected one of the plurality of chambers in the magazine, thereby pushing the cassette out of the chamber and into the DAT drive. A latching means, carried on, and extending beyond, the end of the scissors output arm, is inserted between the cassette and the floor of the chamber containing it, through a slot which runs front-to-back along the floor, and hooks into a recess which is characteristic of DAT cassettes.Type: GrantFiled: May 31, 1990Date of Patent: October 20, 1992Assignee: Distributed Logic CorporationInventor: Douglas R.

Patent number: 4735374Abstract: A supply reel hub for use on a computer tape drive for assuring that a supply reel is squarely locked down and properly aligned on the computer tape drive. The supply hub comprises a locking means in the form of three L-shaped feet for locking the supply reel securely in place, a plurality of spaced apart sensing means and a plurality of signalling means which sense and signal to a controller whether each of the three L-shaped feet of the locking means are properly in position. A centering knob positioned on the top of the supply hub has been provided so that a supply reel may be easily centered over the supply hub. A groove is positioned on the base of the supply hub to allow a write enable tab to slip off of the supply hub and not hang up on the centering knob. Additional sensing means are provided for sensing whether there is a write enable ring on the supply reel. Means for releasably attaching the shaft of the drive motor to the hub base which reduces tape edge damage is also provided.Type: GrantFiled: September 8, 1986Date of Patent: April 5, 1988Assignee: Hewlett-Packard CompanyInventor: Douglas R.
