Abstract: A method is disclosed for connecting a resource-constrained computer device such as a telephone, camera, or personal digital assistant, to a computer network such that the device can make several simultaneous requests to several communications-connected servers. The method allows for the number of requests to exceed the number of physical connection ports available to the device. Allowance is made for failed and cancelled requests, as well as a priority selection from a number of queued requests.

Abstract: An internet-connected digital camera is disclosed, comprising a camera device with connectivity hardware, allowing connection to the Internet, and a web-enabled application program to control the camera. The camera is configured using the web application. Once connected to the Internet (by whatever means), the configuration information is sent from the web application to the camera. The configuration includes image specifications (e.g. color or black and white), trigger specifications (e.g., collect images based on the time or based on motion detection), and connection specifications (e.g., phone number to use to connect via modem). Once installed and configured, the camera collects, then connects and transmits images to the web application to be viewed at a later timer, or viewed in real time. Images may also be sent via e-mail to a specified account.

Abstract: A computationally inexpensive method for determining motion in a digital image stream is disclosed. The method and its software implementation provide good performance in changing light conditions and are achieved by using gradient information between adjacent areas. This gradient is normalised using the intensity or color value of the two areas, such that changing light conditions do not affect the result. The algorithm may be set up include or exclude portions of the view scene.
