Abstract: The present invention pertains to the area of cutting blocks of stone (55, 5) into smaller pieces, through a press. The cutting tool (100) of the present invention is formed by four cutting sections which, together, form a tool which has an open side, oppositely to the prior art solutions. Such open side is provided by the free ends of the two flank cutting sections (203) and of the at least one inner cutting section. By having such free end, not only it is easier to position the tool to cut as it provides a release of the cut piece of stone (55, 5) towards that section, thereby avoiding smashed chips or bits. By having such format, the cutting tool (100) of the present invention allows to avoid waste (51), by cutting a block of stone (55, 5) into one or more pieces using all the block, without leading to waste (51) in each cut.

Title: Methods and compositions for diagnosing and treating rare genetic diseases
Inventor: WILSON KITCH
IPC: C40B30/06
Filed: 2022-01-28
Abstract: Collectively, rare diseases affect approximately 350 million people worldwide, of which half are diagnosed in childhood. Even though more than 80% of rare diseases are genetic in origin and begin  in utero , drug target discovery has historically been stymied due to difficulties in obtaining fetal, neonatal, and pediatric tissues for genetic study and drug discovery. Disease modeling with patient-specific hiPSCs is an ideal platform for both  rapid identification and experimental validation  of early life disease mechanisms. This invention combines high content genomic assays, phenotypic measurements, and machine learning (Artificial Intelligence/Machine Learning) with hiPSC disease models to identify DNA mutations causing early life diseases.

Abstract: Systems and methods for monitoring refrigeration appliances remotely take corrective action to address failure to maintain recurrent maintenance schedules by either pushing a notification to an operator or sending a command to cause a controller (160) of the appliance (103) to switch to a restricted mode. The systems and methods can use periodic indications of ice level from an ice level sensor (141) to determine that the level of ice in the bin is low, and in response, to either push a low ice notification to an operator or place an order for additional ice. The systems and methods can also collect ice level data from many ice makers (103), determine which have a low ice level and which have a high ice level, and in response, facilitate a web based transaction by which one operator acquires ice from another.
