US Classification:

370335, 370336, 370345, 370350, 455434

Abstract:

Embodiments include methods and apparatus associated with wireless multicast and/or broadcast services. A base station (, FIG. ) transmits data codes (, FIGS. -) within a radio frame (, FIG. ). The data codes are Code Division Multiple Access (CDMA) data codes, in an embodiment. The base station also transmits a Time Division Multiplexed (TDM) synchronization code (, FIGS. -), in an embodiment. The base station discontinuously transmits (, FIG. ) a portion of a radio frame slot that is coincident in time with a duration of the TDM synchronization code, in various embodiments. The discontinuously transmitted portion of the radio frame slot may include Transport Format Combination Indicator (TFCI) bits (, FIG. ), pilot bits (, FIG. ), or data bits (, FIG.

US Patent:

Filed:

Oct 19, 2018

Appl. No.:

16/165484

Inventors:

- Coppell TX, US
Kenneth J. Stewart - Coppell TX, US

International Classification:

B41J 2/14
B41J 2/045
B41J 2/16

Abstract:

A method of making inkjet print heads may include forming recesses in a first surface of a first wafer to define inkjet chambers. The method may also include forming openings extending from a second surface of the first wafer through to respective ones of the inkjet chambers to define inkjet orifices. The method may further include forming a second wafer including ink heaters, and joining the first and second wafers together so that the ink heaters are aligned within respective inkjet chambers to thereby define the inkjet print heads.

Appl. No.:

15/664668

Inventors:

- Coppell TX, US
Kenneth J. Stewart - Coppell TX, US

International Classification:

B41J 2/14
B41J 2/16
B41J 2/16

Abstract:

An inkjet print head includes a semiconductor substrate having a plurality of continuous slotted recesses in a first surface. The plurality of continuous slotted recesses is arranged in parallel, spaced apart relation. Each continuous slotted recess extends continuously across the first surface. The semiconductor substrate also has a plurality of discontinuous slotted recesses in a second surface that is opposite the first surface. The plurality of discontinuous slotted recesses is aligned and coupled in communication with the continuous slotted recesses to have a first portion defining a plurality of alternating through-wafer channels and a second portion defining residual slotted recess portions. A dielectric material is disposed within the residual slotted recess portions. A plurality of inkjet heaters is carried by said semiconductor substrate.

Appl. No.:

14/985984

Inventors:

- Coppell TX, US
Kenneth J. STEWART - Coppell TX, US

International Classification:

B41J 2/14

Abstract:

A method of making an inkjet print head may include forming, by sawing with a rotary saw blade, continuous slotted recesses in a first surface of a wafer. The continuous slotted recesses may be arranged in parallel, spaced apart relation, and each continuous slotted recess may extend continuously across the first surface. The method may further include forming discontinuous slotted recesses in a second surface of the wafer to be aligned and coupled in communication with the continuous slotted recesses to define alternating through-wafer channels and slotted recess portions. The method may further include selectively filling the residual slotted recess portions to define through-wafer ink channels.

KENNETH J. STEWART - COPPELL TX, US

International Classification:

B41J 2/16

Abstract:

A method of making an inkjet print head may include forming, by sawing with a rotary saw blade, first discontinuous slotted recesses in a first surface of a wafer. The first discontinuous slotted recesses may be arranged in parallel, spaced apart relation. The method may further include forming, by sawing with the rotary saw blade, second discontinuous slotted recesses in a second surface of the wafer aligned and coupled in communication with the first continuous slotted recesses to define through-wafer channels. In another embodiment, the first and second plurality of discontinuous recesses may be formed by respective first and second rotary saw blades.
