Abstract:
A lubricating system includes a flexible, nominally planar lubricating structure including first and second end regions and a central region positioned therebetween. The lubricating structure is impregnated with a lubricating fluid and is adapted for securement to a printhead carriage only at said first and second end regions.
Compliant Carriage Adjustment Method And Apparatus For Setting Default Printhead-To-Media- Spacing In A Printer

International Classification:
B41J025/308
US Classification:
400/059000, 400/055000, 347/008000
Abstract:
The present invention provides an apparatus for adjusting and fixing default printhead-to-media spacing in a printer having a frame and a printhead-carrying carriage, the apparatus including an elongate, laterally extending carriage rod along which the carriage moves during printing, and selectively adjustable and fixable compliant structure mounting the rod on the frame, and operable to effect positional and fixable adjustment of the rod relative to the frame to establish a desired default printhead-to-media spacing.
A partially-transparent antenna is described that may be utilized to wirelessly transmit or receive data. In one or more implementations, an apparatus includes an antenna and one or more modules implemented at least partially in hardware. The antenna is formed from a material that is at least partially transparent. The one or more modules are communicatively coupled to the antenna to use the antenna to wirelessly transmit or receive data.

Abstract:
The technology provides embodiments for recalibration of outward facing cameras supported by a see-through, head mounted, mixed reality display system having a flexible portion between see-through displays for the eyes. Each outward facing camera has a fixed spatial relationship with a respective or corresponding see-through display positioned to be seen through by a respective eye. For front facing cameras, the fixed spatial relationship allows a predetermined mapping between positions on an image sensor of each camera and positions on the respective display. The mapping may be used to register a position of a virtual object to a position of a real object. A change in a first flexible spatial relationship between the outward facing cameras can be automatically detected. A second spatial relationship between the cameras is determined. A registration of a virtual object to a real object may be updated based on the second spatial relationship.

US Classification:
359630, 29428
Abstract:
A head-mounted display device includes a modular frame assembly including one or more different components. Each of the different components may be selected from a component set including at least two or more differently-sized versions of each different component. The head-mounted display device also includes a modular see-through display sub-assembly including one or more mountings for selectably coupling the modular see-through display sub-assembly to the modular frame assembly. The modular see-through display sub-assembly may be configured to couple to any combination of differently-sized versions of different components of the modular frame assembly.

Abstract:
Multi-antenna systems, including mobile devices having multiple antennas, are provided herein. A first antenna and a second antenna are operable at two or more of the same non-overlapping communication frequency bands. The first antenna and the second antenna are closely spaced and have different fundamental modes of operation such that the first antenna and second antenna are substantially isolated at the two or more non-overlapping communication frequency bands. The first antenna and second antenna having different fundamental modes can be a linear antenna, such as a monopole, dipole, PIFA, or PILA, and an aperture antenna, such as a slot or loop antenna.
