A method may include storing and updating published resource entitlements for a plurality of client devices at a computing device. The method may also include using a plurality of virtual delivery appliances to receive connection requests from the client devices, with the connection requests including connection leases having associated resource entitlements the client devices are respectively permitted to access, and request validation of the connection leases from the computing device. At the computing device, responsive to validation requests from the virtual delivery appliances, the connection leases may be compared to the updated published resource entitlements and validated based thereon. At the virtual delivery appliances, the client devices may be provided with access to virtual sessions corresponding to the published resource entitlements responsive to the virtual session request validations from the computing device.

System and method for validating virtual session requests

A method of fabricating a MEMS inkjet type print head and the resulting device is disclosed. The method includes providing a driver component and separately providing an actuatable membrane component, the actuatable membrane component being formed in the absence of an acid etch removing a sacrificial layer. The separately provided actuatable membrane component is bonded to the driver component and a nozzle plate is attached to the actuatable membrane component subsequent to the bonding. Separately fabricating the components removes the need for hydrofluoric acid etch removal of a sacrifical layer previously required for forming the actuatable membrane with respect to the driver component.

The present invention generally relates to electrical detection of V-groove width during the fabrication of photosensitive chips, which create electrical signals from an original image, as would be found, for example, in a digital scanner or facsimile machine.

Electrical detection of V-groove width

An apparatus detects the width of a V-groove formed on a semiconductor wafer. A resistor overlaps a chip area and an area upon which the V-groove is to be etched on the wafer. A pad etched on the silicon wafer is coupled to the resistor. A tester supplies voltage to the pad after the V-groove has been etched into the silicon wafer; and a circuit coupled to the pad determines the width of the etched V-groove.
