  • Publication number: 20230330761
    Abstract: A method of manufacturing a saw blade includes providing a saw blade body having an edge, forming a plurality of tooth bodies that defines a plurality of gullets in the saw blade body, coupling a cutting member to the edge of the saw blade body, and shaping the cutting member to form a cutting tooth after the cutting member is coupled to the edge. Each one of the plurality of tooth bodies defines an undercut portion positioned between adjacent tooth bodies. The cutting tooth includes a rake face extending from a tip of the cutting tooth toward the saw blade body and a relief face extending from the tip toward a second end of the cutting tooth sloping toward the saw blade body.

  • Patent number: 11659907
    Abstract: A protective cover for a laptop computer having a screen portion and an attached keyboard portion. The cover has a bottom shell for placement on the keyboard portion, or a top shell for placement on the screen portion, or both a bottom shell and a top shell. The cover also has at least one removable locking clip that attaches to the bottom shell when the keyboard portion is placed in the bottom shell, or attaches to the top shell when placed on the screen portion. The locking clip has at least one protruding flange that inserts into a slot in the bottom shell or top shell to internally lock the shell to the keyboard portion or the screen portion. A tool can be inserted into the slot to compress the protruding flange to unlock the bottom shell or top shell from the keyboard portion or the screen portion.

  • Patent number: 11275475
    Abstract: A compliant material, such as a conductive foam, is positioned in the dielectric or capacitive gap between drive and sense electrodes and/or other conductive elements of a capacitive and/or other force sensor, such as a TFT or other display element and a sensor assembly. The compliant material prevents damage by preventing and/or cushioning contact. The compliant material may be conductive. By being conductive and being positioned between the electrodes while still being separated from one or more of the electrodes, the compliant material also shortens the effective electrical distance between the electrodes. As a result, the force sensor may be more sensitive than would otherwise be possible while being less vulnerable to damage.

  • Publication number: 20160139635
    Abstract: A protective case for a hybrid computer having a removable screen and a separable keyboard. The case has a base panel, a lid and a flexible hinge attached to the rear of the base panel and separably connected to the rear of the lid, or attached to the rear of the lid and separably connected to the rear of the base panel, or separably connected to both the rear of the lid and the rear of the base panel. The protective case has separable means for attaching an interior surface of the lid to the removable screen of the computer and separable means for attaching an interior surface of the base panel to the keyboard. The lid can remain attached to the removable screen and the base panel can remain attached to the keyboard when the removable screen is separated from the keyboard.

  • Patent number: 5475800
    Abstract: In liquid-ink color graphics printing, true black ink is preferred over composite black wherever possible, but poor print quality results from printing black ink too close to color ink, due to limitations in present ink chemistry. A method of processing color bit-map graphics data in a four-color liquid-ink printing system, so as to maximize use of black ink while maintaining a minimum spacing between black and color inks is disclosed. The input data is stored in CMY bit-map color planes. Preliminarily, data representing composite black is moved from the color planes into a K plane for printing by a true black pen. The data is examined to detect any black ink within the minimum spacing from color ink. The examination is expedited by partitioning the data into blocks, and indicating each block as a color block, a black block, or a white block. These indications are conveniently stored in a color table and a black table, in which each block of data is represented by a single bit.

A method of processing color bit-map graphics data in a four-color liquid-ink printing system, so as to maximize use of black ink while maintaining a minimum spacing between black and color inks (FIGS. 2-4) is disclosed. The input data is stored in CMY bit-map color planes (54,56,58). Preliminarily, data representing composite black is moved from the color planes into a K plane (60) for printing by a true black pen. The data is examined (66) to detect any black ink within the minimum spacing from color ink. The examination is expedited by partitioning the data into blocks (FIG. 8A), and indicating each block as a color block, a black block, or a white block (FIG. 11).
