Abstract: In a shopping cart having a handle with two generally vertical portions and a generally horizontal portion and having a main basket, a child seat comprises a primary panel, a secondary panel, and a tertiary panel, each panel being made from welded wires. Defining a back panel of the main basket and a front panel of the child seat and being mounted pivotally to the generally vertical portions of thehandle, the primary panel includes generally parallel wires spaced from one another by not more than about two inches. Defining a lower panel of the child seat, thesecondary panel has a substantially open portion and a weight-supporting portion, which includes similarly spaced wires. Below where the primary panel is mounted pivotally to the handle, the secondary panel is mounted pivotally to the primarypanel by several pivot wires extending from the secondary panel. Two pivot wiresdefine two lateral edges of the secondary panel. Three pivot wires divide the substantially open portion into four leg openings for two seated children. Defining a back panel of the child seat, the tertiary panel includes similarly spaced wires and is mounted pivotally to the primary panel, below where the secondary panel is mounted pivotally thereto. The tertiary panel is engaged with the secondary panel so as to limit pivoting of the secondary panel upwardly or downwardly, at the second of the cross wires of the primary panel, and so as to limit pivoting of the tertiary panel away from the primary panel. The tertiary panel is disengageable from the secondary panel.

Title: Kink-resistant braided catheter with distal side holes
Inventor: SAMSON GENE
IPC: A61M25/00
Filed: 1997-05-28
Abstract: This is a catheter section having a number of radially placed holes through the catheter section wall and a catheter assembly including that section. That catheter assembly may be used in accessing and treating a tissue target within the body, typically one which is accessible through the vascular system. Central to the catheter section is the presence of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated in such a way to provide an exceptionally thin wall, controlled stiffness, high resistance to kinking, and complete recovery in vivo from kinking situations. The orifices in the section are optimally placed in theinterstices between the turns of the braid. The braid may have a single pitch ormay vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant. The catheter sections made according to this invention may be used alone or in conjunction with other catheter sections either made using the concepts shown herein or made in other ways. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections due to the presence of stiff polymeric tubing or metallic tubing or composited materials in the stiffer section.

Title: Absorbent article with bolstering waist feature
Inventor: SEITZ BRET DARREN
IPC: A61F13/15
Filed: 1996-01-11
Abstract: Absorbent articles are provided having a bolstering waist feature. In its preferred embodiment, the bolstering waist feature expands upon exposure to aqueous body liquids effectively tightening the diaper by stretching of the waist regions of the absorbent article. There is a resulting increase in the contractive forces in the band of lateral tension in the waist regions of the absorbent article with a corresponding reduction in the risk of waist leakage.  The bolstering waist feature further provides a member resisting longitudinal bending in the waist regions of the absorbent article, particularly adjacent to a wearer's belly. This member can also act as a "strut" resisting the forces, such as those due to gravity, which tend to cause an absorbent article to slide downward. The absorbent article is additionally provided with an absorbent core comprising at least a redistribution component that is preferably capable of redistributing aqueous body liquids from the crotch region to the waist regions of the absorbent article. The redistribution component is in effective fluid communication with the bolstering waist feature.

Title: Multi-level sectorized cdma communications
Inventor: LYNCH MICHAEL A
IPC: H04W16/24
Filed: 1998-01-20
Abstract: A base station of a code division multiple access (CDMA)-based communications network (e.g., one conforming to the IS-95 standard) is sectorized such that, a first subset of CDMA channels are communicated using a first level of cell-site sectorization and a second subset of CDMA channels, different from the first subset, are communicated using a second level of cell-site sectorization, different from the first level. For example, the first set of CDMA channels may be the pilot and sync channels and the second subset of CDMA channels may be the access, paging, and traffic channels. In one set of implementations, at the first sectorization level, each cell site is omnidirectional (for the first subset of CDMA channels), while, at the second sectorization level, each cell site is divided into two or more sectors (for the second subset of CDMA channels). In this set of implementations, each cell site is assigned one pseudo noise (PN) offset and transmits one pilot channel. In another set of implementations, at the first sectorization level, each cell site is divided into two or more sectors (for the first subset of CDMA channels), while, at the second sectorization level, each sector is further divided into two or more sub-sectors (for the second subset of CDMA channels). In this set of implementations, each sector is assigned one PN offset and each cell site transmits a different pilot channel for each sector. In either case, the present invention is able to provide certain advantages of sectorization (e.g., increased capacity and reduced interference) while reducing certain disadvantages of sectorization (e.g., pilot pollution, handoff processing). Moreover, the present invention can be implemented to support existing remote terminals (e.g., mobile,/cellular telephones) having three-finger RAKE receivers.
