Title: Buried heterostructure
Inventor: STOLTZ BJOERN
IPC: H01S5/20
Filed: 1997-02-25
Abstract: An epitaxially grown semiconductor heterostructure has an inner region (5) which is substantially laterally confined by confinement regions (9) and has enhanced transverse confinement by enhanced transverse confinement layers (3, 7). The latter layers are not exposed outside the growth chamber during processing, by stopping the etching for producing the lateral confinement, above the lower enhanced transverse confinement layer (3) and growing such an upper layer (7) after making the lateral confinement regions (9). The structure is intended to be used in particular having the inner region act as an active laser region, for instance in InP-based 1.3 .mu.m wavelength lasers. Then the simultaneous lateral confinement, enhanced transverse confinement and exposure protection enables simultaneously a low threshold current, a small temperature sensitivity and reliable, long life operation. The enhanced transverse confinement layers (3, 7) could comprise aluminium protected from oxidation during processing. Such a laser will then be protected from a declined reliability.

Title: A method of resource management at computer controlled telephony hardware
Inventor: MISTRY DHANSUKH NATHUBHAI
IPC: H04L12/64
Filed: 1999-02-04
Abstract: A method of resource management at computer controlled telephony hardware outside the Public Switched Telephone Network (PSTN) operated by a service provider for establishing a call between a service subscriber and another party by facilitating a PSTN voice connection between the service subscriber and the computer controlled telephony hardware, and a PSTN voice connection between the other party and the computer controlled telephony hardware is described. The method involves determining a resource management index associated with the service subscriber, determining a call treatment using the resource management index, and applying the call treatment to the call. Preferably the call treatment is determined using a rule base which stores a call treatment option for each telephone number or Internet Protocol address associated with a service subscriber. The call treatment options preferably include: a) transfer all calls to the PSTN; b) transfer all toll calls to the PSTN; c) transfer no calls to the PSTN; and d) request instructions on a call-by-call basis to determine whether a call is to be transferred to the PSTN. The advantage is potentially significant savings to the service subscriber on toll charges, and a significant reduction in trunk provisioning requirements for the service provider.

Title: Toilet seat occupancy monitoring apparatus
Inventor: FITZGERALD SANFORD G
IPC: G08B21/22
Filed: 1999-06-11
Abstract: The present invention relates generally to an apparatus for monitoring the occupancy status of a toilet seat. In more particular, it applies to a pressure sensitive switch that can be used in combination with an electronic monitoring device to notify a nearby care-giver or a remote nurse's station that a patient has raised himself or herself from the toilet. Broadly speaking, the instant device is composed of two elements - a pressure sensitive switch and an actuator - that are installed between the toilet seat and the upper rim of the toilet bowl. Pressure on the toilet seat is communicated via the actuator to the pressure sensitive switch which, when compressed, completes an electrical circuit. When the pressure is removed, the electrical circuit is broken, thereby signaling that the patient has risen from his or her seated position on the toilet.
