Publication number: 20120118841Abstract: A holding assembly for aesthetically displaying comestibles comprises a retaining structure and a positioning member. The retaining structure allows the user to firmly secure a comestible to the holding assembly. The retaining structure has two different embodiments: one embodiment for softer comestibles with a flat bottom, such as a cupcake, and another embodiment for more rigid comestibles with a round exterior, such as fruit. The first embodiment of the retaining structure is a platform with tines, and the second embodiment of the retaining structure is a hollow hemisphere with one tine. The positioning member is a long shaft that allows the user to position the comestible in a desired location. The top end of the positioning member is used to attached to the bottom of the retaining structure, and the bottom end of the positioning member is used to penetrate into a base in order to situate the holding assembly.Type: ApplicationFiled: November 15, 2011Publication date: May 17, 2012Inventors: Wendy Lee WEST, Jeffrey J.

Patent number: 7207966Abstract: The present invention provides a fluid retention management system that records and displays fluid retention of a patient based on the weight of fluid entering and exiting the patient's body. Scales or other weighing devices are used to weigh the fluid entering and exiting the body so that the corresponding fluid volume may be calculated. The system automatically detects when a fluid container is being replaced. The fluid deficit of the patient is calculated according to the difference between the fluid volume entering the patient and the fluid volume exiting the patient. An operator is able to enter the specific gravity of the fluid and a fluid deficit alarm threshold. If the fluid deficit exceeds the alarm threshold, audible and visual alarms are generated.Type: GrantFiled: May 10, 2001Date of Patent: April 24, 2007Assignee: Ethicon, Inc.Inventors: George M. Savare, Georgi Lathbury, Jeffrey J. Christian

Patent number: 6616614Abstract: Apparatus for ascertaining cardiac output of the heart of a patient comprising a control and display module. A venous probe is inserted into a vein in the forearm of the patient and is coupled into the control and display module and provides an electrical signal representing the dissolved oxygen in the venous blood. An arterial probe is inserted into an artery in the forearm of the patient and is coupled into the control and display module and provides an electrical output signal representing the dissolved oxygen in the arterial blood. The control and display module has a visible display that provides a continuous in vivo cardiac output that utilizes an arterial venous oxygen differential equation which includes an adjustment factor for adjusting for venous blood being sampled rather than mixed venous blood in the pulmonary artery of the patient.Type: GrantFiled: September 18, 2001Date of Patent: September 9, 2003Assignee: Keimar CorporationInventors: Margaret R.
