    摘要: A method and apparatus for handling small semiconductor devices in the testing of these devices. Multiple devices are mounted within a device strip carrier and are positioned in the testing position. This positioning of the device strip carriers is performed using device strip carrier alignment tools; the device strip carrier can readily be repositioned with respect to the test head/probe card for testing of multiple devices contained within the device strip carrier.

    摘要: A method of conducting transactions in a wireless electronic commerce system, where the system comprises a wireless network operator certification authority (400) having a root public key certificate and at least one attribute authority (404, 405, 406) having a digital certificate that is dependent from the root public key certificate. The attribute authority is accessible by a wireless client device (450, 452) via a wireless network. The digital certificate is delivered from the attribute authority to the wireless device, the attribute authority is verified to the wireless client device using the digital certificate and the root public key certificate pre-loaded in the wireless client device under authority of the wireless network operator. An attribute (software, service, right/permission or other content item) is delivered to the wireless client device over the wireless network and ultimately enabled at the wireless client device.
