Title: Segmented travel baby bottle for powdered formula
Inventor: POPE SARAH
IPC: A61J9/00
Filed: 2009-10-01
Abstract: It is advised by infant formula manufacturers that pre-mixed formula be refrigerated until it is used. This poses a problem when refrigeration may not be possible.  This invention, among other advantages, virtually eliminates the need for refrigeration of pre-mixed powdered formula, particularly while travelling or commuting. This bottle is used for both mixing formula as well as infant feeding and consists of 7 parts, two of which are separate but connected by an apparatus. This apparatus when closed and "locked" keeps two compartments and their contents separate using a water-tight seal.  This apparatus, when opened, or "unlocked," allows for the flow of a pre-measured amount of infant formula into the main body of the bottle and subsequent mixing with sterilized water.

Title: Method of connecting mortgage applicants with financial institutions and mortgage providers using an internet based interest rate auctioning system
Inventor: PALAN VIKAS
IPC: G06Q40/00
Filed: 2010-01-25
Abstract: A method of connecting mortgage applicants with financial institutions and mortgage providers using an internet based interest rate auctioning system. Various 'financial institutions and mortgage providers', hereinafter referred to as 'lenders' register on the central website for an opportunity to place bids on mortgage applications. The borrower fills an online mortgage application form on a central website. The application information is saved in a secure database. With the applicant's permission within the application a credit report is pulled and stored in the secure database. All registered lenders are notified of the new application. Lenders can securely login to the centralised website to review and evaluate the applicant's financial situation. The lenders place a bid on the application with the best interest rate they can provide. Multiple lenders place their best bid on one application. The applicant will choose the most suitable bid made by the lender. The applicants contact information is released to the chosen lender to communicate and proceed further with the application. The chosen lender can send the application data automatically to the mortgage origination and underwriting software systems.  This method enables the applicant to get multiple interest rate options from different lenders saving them time and giving them access to the lowest interest rates based on their financial situation.

IPC: A47C27/18
Filed: 2010-05-04
Abstract: A bladder comprising an outer and inner surface having a length, height and width, first and second ends, and an internal volume. A support structure is disposed within the bladder and has a length, width, height as well as an inner and outer region. The outer region of the support structure comprises support projections which define openings in the outer region of the support structure. The support projections have an engaging end which contacts the inner surface of the bladder and exerts force upon the inner surface of the bladder. The support projections maintain the internal volume of the bladder in a no-load sate. The openings in the support structure allow air to move freely in the bladder versus a solid support structure lacking openings. This aids in distribution of air within the bladder and provides air-like pressure management and comfort in addition to the structural support provided by foam inserts.
