Apr 27, 2006

Appl. No.:

11/412768

Inventors:

David Ho - Cupertino CA, US

International Classification:

H04Q 7/24

US Classification:

370338000, 455433000

Abstract:

The present invention discloses a method for providing a client-requested location dependent information for a designated location through a wireless communication system. The method includes a step of detecting a presence of a wireless network client at the designate location by the wireless communication system wherein the wireless communication system includes a data record of client profile to enable a determination if there is such a client-requested location dependent information for the designated location from the user whereby the client-requested location dependent information may be provided to the client at the designated location through the wireless communication system.

International Classification:

A61M 5/168

US Classification:

604152, 702 47

Abstract:

A pump system and method of detecting/alerting for a possible unintended free flow condition in an administration set includes the steps of a) sampling force signals from a force sensor of the pump at a predetermined frequency; b) storing each of the sampled forces signal in a N-point circular buffer, where N is an integer greater than two; c) calculating a derivative dF/dt based on the two most recent samples; d) repeating step c) and when the most recently calculated derivative dF/dt exceeds a first predetermined threshold, then calculating a N-point moving average of the derivatives dF/dt; and f) when the N-point moving average exceeds a second predetermined threshold, generating a user perceptible alarm to alert the user that a flow stop open condition may have occurred.

Appl. No.:

14/485528

Inventors:

- Menlo Park CA, US
Asad K. Awan - San Francisco CA, US
David Tin Ho Shih - San Francisco CA, US

International Classification:

G06Q 30/02

Abstract:

An online system provides an advertisement (“ad”) request including ad content and a prompt to perform an action presented in association with the ad content. For example, the ad content is video data and the prompt for performing an action is presented after the video data is presented or after a portion of the video data is presented. An advertiser may include a custom prompt in the ad request that includes text information and instructions associated with the text information that perform an action when executed. Multiple prompts may be included in the ad request, and the online system selects a prompt based on information maintained by the online system and associated with a user to be presented with the ad content. The selected prompt is communicated to a client device for presentation in association with the ad content.

Inventors:

- Menlo Park CA, US

David Tin Ho Shih - San Francisco CA, US

International Classification:

G06Q 30/02

Abstract:

An online system may prevent a content associated with a user from including content that is sponsored by a third party, other than the user, for presentation on by the online system unless the user provides an amount of compensation to the online system. To determine an amount of compensation, the online system determines an amount of reach of the content sponsored by the third party based on characteristics of the content associated with the user. For example, a number of users viewing the content associated with the user is used to determine the amount of reach of the content if it is presented by via the content associated with the user. Based on the amount of reach, the online system determines an amount of compensation to be received from the user to present the content sponsored by the third party via the content associated with the user.
