Title: Alarm system for forgotten golf club
Inventor: DAVIS JOHN M
IPC: G08B13/14
Filed: 1999-09-22
Abstract: An alarm system is provided for alerting a golfer about a forgotten club. A  divot tool (20) incorporates a radio transmitter (20E) powered by a rechargeable power source (210) for transmitting a coded transmission. A radio receiver (30E) tuned to receive the coded transmission includes logic circuitry that generates an alarm signal (312, 314, 316) whenever power associated with the coded transmission drops below a threshold level. One or more alarm devices are coupled to the logic circuitry to generate alarm(s) when the alarm signal is supplied thereto. A power source (36) is coupled to the radio receiver for supplying power thereto and for supplying a charging current for the rechargeable power source via an electrical coupling. When a golfer places a club or other accessory on the ground, the divot tool is placed near the club. As long as the golfer remains within a prescribed range, no alarm will be activated. However, if the golfer moves further from the divot tool than the prescribed range, an alarm is produced. Alerted to his forgetfulness before leaving the vicinity, the golfer then simply retrieves the club and divot tool.

Title: Production of attenuated negative stranded rna virus vaccines from cloned nucleotide sequences
Inventor: DURBIN ANNA P
IPC: C07K14/135
Filed: 2000-04-12
Abstract: Attenuated, recombinant negative stranded RNA viruses suitable for vaccine u se are produced from one or more isolated polynucleotide molecules encoding the  virus. A recombinant genome or antigenome of the subject virus is modified t o encode a mutation within a recombinant protein of the virus at one or more amino acid positions(s) corresponding to a site of an attenuating mutation i n a heterologous, mutant negative stranded RNA virus. A similar attenuating mutation as identified in the heterologous negative stranded RNA virus is th us incorporated at a corresponding site within the recombinant virus to confer an attenuated phenotype on the recombinant virus. The attenuating mutation incorporated in the recombinant virus may be identical or conservative in relation to the attenuating mutation identified in the heterologous, mutant virus. By the transfer of mutations into recombinant negative stranded RNA viruses in this manner, candidate vaccine viruses are engineered to elicit a  desired immune response against a subject virus in a host susceptible to infection thereby.

Abstract: In a tree-structural key distribution system, renewed data of a master key and medium key are sent along with a key renewal block (KRB). KRB is such that each of devices included as leaves of a tree structure has a leaf key and restricted node key. A specific KRB can be generated for a group identified by a specific node and distributed to the group to restrict a device for which the key can be renewed. Any device not belonging to the group cannot decrypt the key, whereby the security of key distribution can be assured. Especially in a system using a generation-managed master key, a master key renewed with KRB can be distributed.

Abstract: The object of this invention is to make life easier for the parents of newborns. Heartbeat sound is known to produce a calming and soothing effect on newborns.  This becomes more effective when it is the mother's identical heartbeat, which the infant came to know during gestation. This invention provides a practical method for the mother to record her own heartbeat. This is played back by a device automatically activated by the crying of the baby and remains activated for a predetermined period after the crying stopped. The object is to lure the baby into believing that his/her mother is present when needed based on hearing comforting heartbeats even she is not physically present. The recorded mother's heartbeat is achieved by the use of a stethoscope fitted with a diaphragm in one end of the acoustical tube and the other end plugs in a record microphone of the device.
