Patent number: 11808492Abstract: A cooling system employs at least one composite elastocaloric device. Each composite device has a first member with a first material and a second member with an elastocaloric material. The first material increases in size in response to an applied electric or magnetic field and returns to its prior size upon removal of the applied electric or magnetic field. The first and second members are mechanically coupled together such that the increase in size of the first material applies a stress to the elastocaloric material and the return of the first material to its prior size releases said stress, thereby causing the elastocaloric material to absorb heat.Type: GrantFiled: September 25, 2019Date of Patent: November 7, 2023Assignees: University of Maryland, College Park, The Government of the United States of America, as represented by the Secretary of the NavyInventors: Huilong Hou, Ichiro Takeuchi, Margo Staruch, Peter Finkel

Patent number: 10823465Abstract: A system for heating/cooling includes a plurality of thermoelastic modules. Each of the modules includes one or more structures formed of shape memory alloy, which converts from austenite to martensite upon application of a first stress and release latent heat from the conversion. During a first part of a heating/cooling cycle, a first module is stressed to cause conversion. The latent heat released from the first module is rejected to a heat sink while a second unstressed module absorbs heat from a heat source. During a second part of the heating/cooling cycle, the first and second modules are connected together to transfer heat therebetween for heat recovery. The cycle can be repeated indefinitely with the first and second modules alternating roles. Structures of the thermoelastic cooling material and specific applications thereof are also disclosed.Type: GrantFiled: June 2, 2018Date of Patent: November 3, 2020Assignee: University of Maryland, College ParkInventors: K.

Patent number: 10323865Abstract: A compact cooling system based on thermoelastic effect is provided. In one embodiment, the system comprises a pair of rollers serving as a heat sink, stress applicator and belt drive, a cold reservoir and a solid refrigerant belt coupled to the cold reservoir and to the heat sinks to pump heat from the cold reservoir to the heat sink. The refrigerant belt comprises solid thermoelastic materials capable of thermoelastic effect. The refrigerant material is mechanically compressed when entering the gap of the roller and subsequently released after passing through. When compressed the refrigerant material transforms to martensite phase and releases heat to the roller and neighboring materials. After released by the rollers, the refrigerant material transforms back to austenite and absorbs heat from the ambient atmosphere.Type: GrantFiled: November 10, 2016Date of Patent: June 18, 2019Inventors: Jun Cui, Ichiro Takeuchi

Patent number: 8576062Abstract: A driving advice provision apparatus generates an advice, based on diagnosis performed on multiple diagnosis items regarding the driving condition of the vehicle and based on the diagnosis results from those diagnosis items, and provides the generated advice to the driver. The multiple diagnosis items are classified into different categories according to the diagnosis methods. For the diagnosis items suitable to the comparative evaluation rather than the quantitative evaluation, a diagnosis result A for the previous evaluation section is compared with a diagnosis result B for the current evaluation section for yielding a comparative evaluation and for advice generation, thereby enabling an effective advice generation and provision in terms of diagnosis item category.Type: GrantFiled: July 31, 2009Date of Patent: November 5, 2013Assignees: Denso Corporation, Toyota Jidosha Kabushiki KaishaInventors: Kousuke Yamaoka, Ichiro Takeuchi, Shojiro Takeuchi
