US Patent:

47712953, Sep 13, 1988

Filed:

Jul 1, 1986

Appl. No.:

6/880774

Inventors:

Jeffrey P. Baker - San Diego CA
Duong T. La - San Diego CA
Randy A. Coverstone - Newark CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

G01D 1518

US Classification:

346 11

Abstract:

The novel pen body construction described herein includes multiple ink storage compartments communicating with a multi-orifice printhead, and these compartments are adapted to receive sections of ink-storage foam. Preferably, this foam is a reticulated polyurethane foam of controlled porosity and capalarity and is especially well suited for storing different ink colors, such as cyan, magenta and yellow. However, single compartment black ink storage is also within the scope of this invention.

Abstract:

A disposable thin film resistor type thermal ink jet pen including a housing having a support surface at one end thereof with openings for passing ink to an adjacent thin film resistor type thermal ink jet printhead. The printhead is mounted on the support surface and has ink ejection orifii therein communicating with openings in the support surface. A porous foam material is mounted within the housing and is operative to receive and retain a supply of ink for feeding the ink by capillary action through the openings in the support surface and to the ink jet printhead. The foam ink storage material is compressed in one or more compartments of the housing to reduce the pore size therein and reduce the foam thickness while increasing its density. By this process, the capillary force of the foam is increased and thereby renders this ink storage medium especially well-suited for feeding ink on demand to a thin film resistor type of thermal ink jet printhead.

International Classification:

G01N 1502

US Classification:

738655

Abstract:

A dry particle analyzer includes a vibrating sieve cup drizzling particles downwardly with first and second sheath air flows provided to separate the particles from boundary walls and to form the drizzling particles into a curtain for optical analysis. The particles drop vertically as a drizzle with gravitational assistance from a bulk sample to the analysis passage, after which their direction of movement is changed to horizontal and then upward for removal from the analyzer.

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

C09D 1102

US Classification:

106 22

Abstract:

A method for improving the print quality of ink used in ink-jet printers, particularly thermal ink-jet printers, is provided. For an ink typically comprising about 90 to 98 wt % water and about 10 to 2 wt % diethylene glycol plus about 0. 1 to 12 wt % dye, the improvement is achieved by adding an additive consisting essentially of about 1 to 30 wt % ethanol, about 1 to 30 wt % n-propanol, about 1 to 10 wt % iso-propanol, or about 0. 002 to 0. 05 wt % of 2,5,8,11-tetramethyl-6-dodecyn-5,8-diol.

Abstract:

An apparatus and method of generating personalized HRTFs. The system is prepared by calculating a model for HRTFs described as the relationship between a finite example set of input data, namely anthropometric measures and demographic information for a set of individuals, and a corresponding set of output data, namely HRTFs numerically simulated using a high-resolution database of 3D scans of the same set of individuals. At the time of use, the system queries the user for their demographic information, and then from a series of images of the user, the system detects and measures various anthropometric characteristics. The system then applies the prepared model to the anthropometric and demographic data as part of generating a personalized HRTF. In this manner, the personalized HRTF can be generated with more convenience than by performing a high-resolution scan or an acoustic measurement of the user, and with less computational complexity than by numerically simulating their HRTF.

Abstract:

One or more context aware processing parameters and an ambient audio stream are received. One or more sound characteristics associated with the ambient audio stream are identified using a machine learning model. One or more actions to perform are determined using the machine learning model and based on the one or more context aware processing parameters and the identified one or more sound characteristics. The one or more actions are performed.
