Abstract: Systems, computer-readable instructions, and methods for storing products are disclosed. For example, the system may include modular shelving units that include a shelf which is placeable on a rack, the shelf including a platform, the shelf having a weight sensor below the platform, the platform is configured to support N number of holders, each of the N holders configured to store products, each shelf further having N?1 optical sensors below the N?1 holders when the N?1 holders are supported by the platform and N?1 windows above the N?1 optical sensors, the N?1 optical sensors being in proximity of the N?1 holders, respectively, wherein each holder includes an opening, wherein when a holder is on the shelf, the opening is capable of being aligned with an optical sensor, the shelf further having a processing circuit coupled to the N?1 optical sensors and the weight sensor.

Abstract: Disclosed are weighted shoe assemblies that allows easy selection of different weights and the ability to accommodate a variety of foot or shoe sizes. This greatly reduces the cost of providing all sizes and shapes of individually fitted shoes. More specifically disclosed are weighted shoe assemblies having an upper attachment component to attach to a user's foot or shoe and a removable weight components to allow selection of desired weights and means to removably attach the components together.

Abstract: An adapter for pressure sensors for monitoring long-term cylinder pressures in internal combustion engines comprises a housing with a gas duct, a connection to a cylinder cover of an internal combustion engine, a rear opening of the gas duct from the housing with an apparatus for closing this rear opening in a gastight manner, and a connection for inserting a pressure sensor with a sensor membrane. The transition line of the opening in the gas duct, which is reached by the sensor membrane in the inserted state in order to be exposed to the gas pressure in the gas duct, is on a plane. The transition line forms the transition from the contour of the gas duct to the connection to the sensor. There is a continuous transition from the sensor membrane to the contour of the gas duct.

Abstract: The invention relates to an adapter for pressure sensors for monitoring long-term cylinder pressures in internal combustion engines, said adapter comprising a housing 1 with a gas duct 2, a connection 3 to a cylinder cover of an internal combustion engine, a rear opening 11 of the gas duct 2 from the housing 1 with an apparatus 12 for closing this rear opening 11 in a gastight manner, and a connection 4 for inserting a pressure sensor 5 with a sensor membrane 6. The idea underlying the invention is that the transition line 8 of the opening 7 in the gas duct 2, which is reached by the sensor membrane 6 in the inserted state in order to be exposed to the gas pressure in the gas duct 2, is on a plane. The transition line 8 forms the transition from the contour of the gas duct 2 to the connection to the sensor 5. This enables a continuous transition from the sensor membrane 6 to the contour of the gas duct 2.
